1. I type in something into the combobox, which brings up all matching options and I select one of the matching options. This sets the combobox text to the selected item's text.
2. Now, I focus out of the combobox, and then come back to combobox and delete all the text, but not select another item. **The combobox is showing blank text even though the selected value is there.** This appears not very intuitive to me as a blank text should mean no option is selected.
A video illustrating this problem can be found here: [http://screencast.com/t/QLUtZYsL2][1]
**This is what I am aiming for in above use case:**
I want to make sure that in case the user somehow deletes the combobox text, then on leaving the combobox, the text gets restored to selected item's text.

Background:
I have an object in my html that embeds is a .mov file like so:
<object CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab" classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" width="100%" height="100%" class="movie1" id="movie1ie">
<param name="src" value="movies/test.mov">
<param name="autoplay" value="false">
<param name="loop" value="false">
<param name="controller" value="false">
<!--[if !IE]>-->
<object type="video/quicktime" data="movies/test.mov" width="100%" height="100%" class="movie1" id="movie1">
<param name="autoplay" value="false">
<param name="loop" value="false">
<param name="controller" value="false">
</object>
<!--<![endif]-->
</object>
And it seems to be okay, until I want to play the movie with a call to javascript. I am using jQuery so I tried this from within a function:
function startMovie(1){
var playIt = 'movie'+ whom;
$('#' + playIt).get(0).play();
}
But then I get this error:
Uncaught TypeError: Object #<HTMLObjectElement> has no method 'play'
Weird, but I'm no jQuery ninja so I tried to call it using good ole javascript:
function startMovie(1){
var playIt = 'movie'+ whom;
document.getElementById(playIt).Play();
}
But now I get the following error in my console:
Uncaught Error: Error calling method on NPObject.
Which is very wierd, since if I put the following into my console the movie will start playing without errors:
document.getElementById('movie1').Play()
FWIW I am using Chrome on a Mac and the files are running on the local machine (no server).

I am using a custom Set class that is basically the same as the STL Set class
The problem is that I am somehow implementing it incorrectly and the default comparison function is used rather than a comparison I defined.

Does anyone know what could be causing the problem?
btnFold = (Button)findViewById(R.id.btnFold);
btnFold.setVisibility(View.VISIBLE); | 0 |

Customer server return for me data in JSON format. But now JSON doesn't have full information.
What I plan:
First one I need some secret key that I will send to server. This key will use for first request. In response I will get JSON with new secret key that I will use for each other request. This is some secret key for unique user. Also for example in response I will get some user id.
So next step is encode. I think i need encode my request with md5 function (I know how it work).
Well, what I have now:
Secret key in app (that will encode before sending on the server).
Secret key (the same as token as I think) which will using for each request.
But this is just my "draft" how I can make it. Can you describe your method how to authorize user using JSON, secret, md5 and etc. I need just figure out with a scheme how I can make it.

The image provided will consist of all empty parking spaces. I have read several posts and tutorials about this. So far, the approach I have tried are:
1.Convert image to grayscale using `cvtColor()`
2.Blur the image using `blur()`
3.Threshold the image to get edges `threshold()`
4.Find image contours using findContours()
5.Finding all convex contours using `convexHull()`
6.Approx polygonal regions using `approxPolyDP()`
7.Get the points for the result from 5, if total number of points =4.
Check for area and angle.
I guess the problem with this approach is when I do `findContours()`, it finds irregular and longer contours which causes `approxPolyDP` to assume quadrilaterals larger than the parking space itself. Some parking lines have holes/irregularity.
I have also tried `goodFeaturesToTrack()` and it gives corners quite efficiently, but the points stored in the output are in arbitrary order and I think it is going to be quite rigorous to extract quadrilaterals/rectangles from it.
I have spent quite good hours on this. Is there any better approach to this?

My graphic card is a NVidia GeForce GT 425M. I made my experiments on a Ubuntu 12.04 with the NVidia driver 295.40.
I Create a QMainWindow containing two QGraphicsView, each graphics view are displaying the same scene. On One of the Graphics View, I setup an OpenGL View port.
The OpenGL View Port is a QGLWidget I had overloaded with the loading of the vertex and fragment shader programs.
Look at my QMainWindow constructor :
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
m_scene = new QGraphicsScene(this);
ui->gvShaded->setScene(m_scene);
ui->gvUnshaded->setScene(m_scene);
m_glWidget = new QGLScene();
ui->gvShaded->setViewport(m_glWidget);
m_glWidget->updateGL();
if(m_glWidget->context()->isValid())
{
qDebug()<<"GL Context is valid";
}else
{
qWarning()<<"GL Context is not valid";
}
qDebug() << "Opengl Version : " << m_glWidget->context()->format().openGLVersionFlags();
QBrush brush(QLinearGradient(0,0,20,0));
brush.setColor(Qt::blue);
QGraphicsRectItem* rect = m_scene->addRect(0,0,20,20,QPen(Qt::black), brush);
ui->gvShaded->ensureVisible(rect);
ui->gvUnshaded->ensureVisible(rect);
}
As you can see I instantiate the object QGLScene which is :
class QGLScene : public QGLWidget
{
public:
QGLScene(QWidget* _parent=0);
protected :
virtual void initializeGL();
};
My GLWidget Construction is :
QGLScene::QGLScene(QWidget *_parent)
:QGLWidget(QGLFormat(QGL::DepthBuffer), _parent)
{
}
And definition of initializeGL is :
void QGLScene::initializeGL()
{
qDebug() << __PRETTY_FUNCTION__;
QGLShader fragmentShader(QGLShader::Fragment, context(), this);
QGLShader vertexShader(QGLShader::Vertex, context(), this);
QGLShaderProgram pgm(context(), this);
if(vertexShader.compileSourceFile("./vertexShader.glsl"))
{
if(fragmentShader.compileSourceFile("./fragmentShader.glsl"))
{
pgm.addShader(&fragmentShader);
pgm.addShader(&vertexShader);
pgm.link();
pgm.bind();
qDebug() << "Shader bien chargé : "<< pgm.log();
}else
{
qDebug() << "Problem when loading fragment shader :";
qDebug() << fragmentShader.log();
qDebug() << QString(fragmentShader.sourceCode());
}
}else
{
qDebug() << "Problem when loading vertex shader :";
qDebug() << vertexShader.log();
qDebug() << QString(vertexShader.sourceCode());
}
}
My shaders are very useless shaders :
Vertex :
#version 150
uniform mat4 viewMatrix, projMatrix;
in vec4 position;
in vec3 color;
out vec3 Color;
void main()
{
Color = color;
gl_Position = projMatrix * viewMatrix * position ;
}
Fragment :
#version 150
in vec3 Color;
out vec4 outputF;
void main()
{
outputF = vec4(1.0, 0, 0, 1.);
}
So I attempt to have my Shaded Graphics view as a big red square because I think I enforced the pixels to be red (in my fragment shader).
I have no shader compilation error, but my two scene are the same.
Of course, the program pass into the initializeGL function (I can read the __PRETTY_FUNCTION__).
Does some one have an explanation ?

**What I'm trying to do**
----------
I'm trying to create a chat which has to diffrent row's. For every row I made a own layout file, but the problem is that the layoutfile of one row dosn't fit the screen.
**Question**
----------
What do I need to change in the row layout that it fits like it should. You'll find the code and also a printscreen of what I'm trying.

See code below. It uses UiApp and builds a vertical panel with radio buttons and a submit button to allow the user to pick a row color. The code for the menu that calls ColorStatus() is not included.
The problem is in the handler function called function "b". Suddenly, I can never get the correct active range or cell or row or column. The user chooses a radio button (color), clicks submit, and the submit calls the function "b". The vertical panel closes and the function b code tries to identify the current row and color it based on the radio button selection. However, using getActiveRange() or getRow() always point to cell A1, and will only colorize the first row of the spreadsheet.

I am trying to write a code to search through a series of cell ranges for a specific value-- if that value exists in the range I want it to insert a 1 into an array, and if it doesn't to insert a 0.
My data look something like:
**Item R1 R2**
1121 1 3
1121 2
1121
1121 3 2
1121 3
1122 4 5
1122 3 5
1122 5
1122 4
1122 5
My end goal is to be able to sum the values in the array and count the total number of items with each rating. For example, in the sample above I would want to be able to produce:
> Number of Items with Rating of 1 = 1
>
> Number of Items with Rating of 2 = 1
>
> Number of Items with Rating of 3 = 2
>
> And so on.
The code I wrote was:
Sub Items()
Dim myArray() As Variant
Dim i As Integer
Dim k As Integer
i = 0
k = 0
R5 = Range("G(2+k):H(6+k)")
mycount = Application.WorksheetFunction.Sum(myArray)
Sheets("Operational").Select
For Each R5 In Range("G2:H206")
ReDim myArray(0 To i)
myArray(i) = Cell.Value
i = i + 1
k = k + 4
R5.Select
If R5.Value = "1" Then
myArray(i) = 1
Else
myArray(i) = 0
End If
Next
End Sub
I have 5 rows for each item so I thought I could approach this as a repeating, consistent loop. However I get an error when I try to run it - "Application-defined or object-defined error."
I know this is probably not the best way and I am so new to this I don't know where to start in troubleshooting. Any help would be much appreciated.
Also if anyone has a good reference for VBA structure/code or a beginner's tutorial, let me know! I haven't had much luck in finding any good references. | vba | excel-vba | null | null | null | null | open | VBA - If Range Includes Value Then Array(i) = 1, Loop, Sum

1)My AppDelegate has the normal indication: self.window.rootViewController = self.viewController;
2) viewController is the delegate of a UITextView (which has its own .h and .m files).
3) When you click on the selected text (viewController handles this activity), a popover shows up with a tableView inside. The tableViewController of that table view initializes and gets its cells values depending on information given by viewController processes
4) When you click on a row of the tableView, a navigator pushes to a new tableView. The new tableViewController initializes and its cells get values depending on information given by the first tableViewController
5) When you click on a row of this second tableView, the popover should disappear and the UITextView text has to get values depending on the information given by the last tableViewController
I have had no problem with showing the popover from the text selected and the tableView inside of it. I have neither had problems with navigating to the other table view. The problems are:
1) In order to pass information to the first table view, I had to create a method inside the first view controller InitWithNib:bundle:Info, where Info is the viewController process result and the method returns the default InitWithNib method, in order to send the information to that ViewController. I don't know if that is correct or I should try to run the processes directly in the tableViewController.
2) Same as the first problem: in the second tableViewController I created a InitWithNib:bundle:Info method to send the information needed to fill the cells, using the information given by processes run in the first table view controller. I don't know if thats the correct way or reflects a bad architectured program.
3) I could change the text depending on the information given by the last tableViewController using global variables, but I know thats a bad practice and reflects bad architectured program.
Please suggest me a good architecture to solve this using good practices, I've been researching for 3 days and have found no good answers,

I'm using a two jsTrees on the same page, (Available objects on the left and Included objects on the right) and i have several buttons in the middle that let users move objects from the left tree to the right tree and vice versa. I'm not using the dnd plugin and don't intend for users to be able to drag and drop between trees. My data structure is only two levels deep, parents and children/multiple children.
The other thing to mention is when i move a node from one tree to another, it is removed from that tree and created in the other tree.
So then problem i'm having is, i can select a node in the left tree (either a parent or one of its children) and i can move it to the right tree after clicking the button. If the node i selected is the parent, it moves the parent and all children. If the node i selected is the only child, it moves both the parent and the child. Lets stick with this scenario for this example. I do this by the following:
//Check to see if the parent exists in the right tree, if it doesn't create it
I've left this function call out for now but can post later if required
//Assuming the parent doesn't exist, create the parent in the right tree
$("#treeInc").jstree("create", null, false, { attr: { id: parent.id }, data: $(parent).children("a").text() }, false, true);
//Create the child in the right tree belonging to the parent node
$("#treeInc").jstree("create", $("#" + parent.id), "inside", { attr: { id: child.id }, data: $(child).children("a").text() }, false, true);
//Remove the parent and child from the left tree
$("#treeAvail").jstree("remove", $('#' + child.id));
$("#treeAvail").jstree("remove", $('#' + parent.id));
Now this all works great but the problem i have is when i try to move the nodes back to the left tree the parent always seems to exist in the data even thought is should have been removed. This means that i dont actually call the code to create the parent but only the child and it ends up hanging around on its own with no parent in sight.
So my logic is to first check to see if the parent exists by basically looking for the parent id in the nodes belonging to the right tree. I've done this several different ways so far and each time i fail.
I have called the 'get_json' function of the left tree to loop through the nodes but it exists in there.
I loop round the array that i initially loaded the left tree from but that has all the nodes in from the initial load and never seems to change.
I've tried to use 'delete_node' instead of remove but that makes no difference.
So what am i doing wrong? If i remove a node from a jsTree, in terms of data, how could i check that tree to see that it has gone?
Please help, its driving me mad!!!
My actual tree data comes from a web service but for this example, the below json array will do.
availDataCache = [
{ attr: { id: "A_R1" }
, data: "Report 1"
, state: "open"
, children: [{ attr: { id: "A_PSA1" }, data: "Param Set A"}]
}
, { attr: { id: "A_R2" }
, data: "Report 2"
, state: "open"
, children : [
{ attr: { id: "A_PSA2" }, data: "Param Set A" }
,{ attr: { id: "A_PSB1" }, data: "Param Set B" }

| jquery-plugins | jstree | null | null | null | null | open | jsTree removing node isn't actually removing it
===
hope you can help with a jsTree issue i'm having... only recently started to use it so still finding my feet.
I'm using a two jsTrees on the same page, (Available objects on the left and Included objects on the right) and i have several buttons in the middle that let users move objects from the left tree to the right tree and vice versa. I'm not using the dnd plugin and don't intend for users to be able to drag and drop between trees. My data structure is only two levels deep, parents and children/multiple children.
The other thing to mention is when i move a node from one tree to another, it is removed from that tree and created in the other tree.
So then problem i'm having is, i can select a node in the left tree (either a parent or one of its children) and i can move it to the right tree after clicking the button. If the node i selected is the parent, it moves the parent and all children. If the node i selected is the only child, it moves both the parent and the child. Lets stick with this scenario for this example. I do this by the following:
//Check to see if the parent exists in the right tree, if it doesn't create it
I've left this function call out for now but can post later if required
//Assuming the parent doesn't exist, create the parent in the right tree
$("#treeInc").jstree("create", null, false, { attr: { id: parent.id }, data: $(parent).children("a").text() }, false, true);
//Create the child in the right tree belonging to the parent node
$("#treeInc").jstree("create", $("#" + parent.id), "inside", { attr: { id: child.id }, data: $(child).children("a").text() }, false, true);
//Remove the parent and child from the left tree
$("#treeAvail").jstree("remove", $('#' + child.id));
$("#treeAvail").jstree("remove", $('#' + parent.id));
Now this all works great but the problem i have is when i try to move the nodes back to the left tree the parent always seems to exist in the data even thought is should have been removed. This means that i dont actually call the code to create the parent but only the child and it ends up hanging around on its own with no parent in sight.
So my logic is to first check to see if the parent exists by basically looking for the parent id in the nodes belonging to the right tree. I've done this several different ways so far and each time i fail.
I have called the 'get_json' function of the left tree to loop through the nodes but it exists in there.
I loop round the array that i initially loaded the left tree from but that has all the nodes in from the initial load and never seems to change.
I've tried to use 'delete_node' instead of remove but that makes no difference.
So what am i doing wrong? If i remove a node from a jsTree, in terms of data, how could i check that tree to see that it has gone?
Please help, its driving me mad!!!
My actual tree data comes from a web service but for this example, the below json array will do.
availDataCache = [
{ attr: { id: "A_R1" }
, data: "Report 1"
, state: "open"
, children: [{ attr: { id: "A_PSA1" }, data: "Param Set A"}]
}
, { attr: { id: "A_R2" }
, data: "Report 2"
, state: "open"
, children : [
{ attr: { id: "A_PSA2" }, data: "Param Set A" }
,{ attr: { id: "A_PSB1" }, data: "Param Set B" }
]
}
];
$("#treeAvail").jstree({
"json_data": {
"data": availDataCache
},

In this form I have 2 choice lists, one to select the name of a Company et one to select the employees.

It seems that the validator take the default value of company and store the list of its employyes and when I change the company (and so the employee list change) the validator doesn't valid because every current employees are not in the previous list.

I have a column there that consist of the following data:
- 50595855
- 59528522
- C_213154
- 23141411
The problem is that when I read this column the reader shows me that the third row is empty. The column format in Excel is set to 'General'. But when I set the format to 'Text', everything works fine and reader sees the data in that row.
So just for a sake of experiment, I prefixed first two rows with letter and made it look like following :
- C_50595855
- C_59528522
- C_213154
- 23141411
And the reader reads everything without problem even when the column format is set to 'General'.
So Excel apparently somehow analyses data in the column before loading it, and it gets confused when first cells of the column look like numeric and some of the rest are texts..
It is really weird to me as either there is data in the cell or there isn't.
Anyone have any ideas why this is happening?
Any help will be much appreciated.

Imagine the following models (simplified):

Column('tag_id', Integer, ForeignKey('tags.id'))
)

My approach to count the amount of entries for a tag is `len(db_session.query(Tag).get(1).entries)`. The problem is that when it gets `db_session.query(Tag).get(1).entries` SQLAlchemy selects all the entries with all their columns for a tag, however, I want only the amount of the entries, not the entries themselves. Is there a more optimal approach for this problem?

===
As you can see from the code, within my callback I extract out the audio data and place it into NSData data, then send that off to another class to upload that to the server. This all works, meaning the server receives and plays the audio data. HOWEVER there is a clicking or tapping noise between the buffers. I am hoping someone might show me what is causing that and how it can be fixed.
I have read other related postings however they all seemed to refer to only using 1 buffer and that adding more was the fix but I am using 3 buffers and have tried adjusting that number which did not fix it

It is supposed to copy an AnimatedSprite. I'm having second thoughts that it has the unfortunate side effect of changing the *this object.
How would I implement this feature without the side effect?
public:
AnimatedSprite& AnimatedSprite::Clone(const AnimatedSprite& animatedSprite) {
return (*this = animatedSprite);
}
protected:
AnimatedSprite& AnimatedSprite::operator=(const AnimatedSprite& rhs) {
if(this == &rhs) return *this;
destroy_bitmap(this->_frameImage);
this->_frameImage = create_bitmap(rhs._frameImage->w, rhs._frameImage->h);
clear_bitmap(this->_frameImage);
this->_frameDimensions = rhs._frameDimensions;
this->CalcCenterFrame();
this->_frameRate = rhs._frameRate;
if(rhs._animation != nullptr) {
delete this->_animation;
this->_animation = new a2de::AnimationHandler(*rhs._animation);
} else {
delete this->_animation;
this->_animation = nullptr;
}
return *this;

i.e.
['a', 'b', 'ab', 'abc']
becomes
[['a', 'b'], ['ab'], ['abc']]
I've accomplished this like so:
lst = ['a', 'b', 'ab', 'abc']
lsts = []
for num in set(len(i) for i in lst):
lsts.append([w for w in lst if len(w) == num])
I'm fine with that code, but I'm trying to wrap my head around comprehensions. I want to use nested comprehensions to do the same thing, but I can't figure out how. | python | nested | comprehension | null | null | null | open | Python: split list of strings to a list of lists of strings by length with a nested comprehensions
