Resize a QDockWidget width ?

? Offline

Hi,
I have a problem with my QDockWidget, I want it to take all available width space. But it only takes the minimum space...

This is the source code that I do :

[CODE]//testWidget.h
class testWidget : public QWidget
{
Q_OBJECT

public:
explicit testWidget(QWidget *parent = 0);
QLabel test;
QPushButton testButton;

};[/CODE]

[CODE]//testWidget.cpp
testWidget::testWidget(QWidget *parent) :
QWidget(parent)
{
setStyleSheet("background-color: yellow");

test.setText("test label");
test.setParent(this);
test.setVisible(true);

testButton.setText("TestButton");
testButton.setParent(this);
testButton.move(0, 20);
testButton.setVisible(true);

}[/CODE]

[CODE]//mainWindow.h
class mainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit mainWindow(QWidget *parent = 0);
testWidget *testW;
};[/CODE]

[CODE]//mainWindow.cpp
mainWindow::mainWindow(QWidget *parent)
: QMainWindow(parent)
{
setFixedSize(1000, 900);

QLabel *test = new QLabel;
test->setFixedSize(500,900);
test->setStyleSheet("background-color: black;");
setCentralWidget(test);

testW = new testWidget;

QDockWidget *dock = new QDockWidget("DOCKTEST", this);
dock->setFeatures(QDockWidget::DockWidgetMovable | QDockWidget::DockWidgetFloatable);
dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);
dock->setWidget(testW);
addDockWidget(Qt::RightDockWidgetArea, dock);

}[/CODE]

The result is:

And I want that :

So, if someone can help me, it will be very great !

Thanks in advance for your help,

You need to implement the sizeHint() function in your custom widget and use a sensible sizePolicy that will give you the layout that you want.

If you are not locked into using a dock widget then a QSplitter might be an easier way.

You need to use Qt layout functionality if you want Qt to do anything to layout/resize the content of your widgets.
