QDockWidget-title

[jpn]

Somehow this doesn't do the trick. I already have installed an eventFilter(paint event) on the qdockwidget and I applied the code to it but it doesn't show. Any other ideas??

Painting in an event filter is a bit problematic because the event goes FIRST through the filter and THEN to the base class (assuming that the event filter doesn't filter it out). So basically the base class draws over anything you had drawn in the event filter. This kind of painting is possible in event filter only by doing some ugly tricks. Basically you have to deliver the event to the receiver widget by hand and then do the custom painting afterwards. And you will also have to temporarily remove the event filter to avoid an infinite loop.

// this is inside an event filter where event type is a paint event..
 
// remove the event filter during sending
// the paint event to avoid an infinite loop
widget->removeEventFilter(this);
 
// send the event and let the widget to draw itself first
QApplication::sendEvent(widget, event);
 
// restore the event filter
widget->installEventFilter(this);
 
// draw your custom things here
QStylePainter painter(widget);
....
 
// be sure to return true so that the widget doesn't
// receive this paint event and paint itself over again
return true;

// this is inside an event filter where event type is a paint event..

// remove the event filter during sending
// the paint event to avoid an infinite loop
widget->removeEventFilter(this);

// send the event and let the widget to draw itself first
QApplication::sendEvent(widget, event);

// restore the event filter
widget->installEventFilter(this);

// draw your custom things here
QStylePainter painter(widget);
....

// be sure to return true so that the widget doesn't
// receive this paint event and paint itself over again
return true;

So, I recommend you to simply subclass QDockWidget and override paintEvent()... it will be much simplier and less error prone..

I have another problem conserning QDockWidget. In my workspace i have tvo dockwidgets and one other widget. The problem is that these two widgets have their own PE_IndicatorDockWidgetResizeHandle and I only need one. I know how to disable them both but i don't know how to disable just one.

i tried this code but it doesn't work (if i remove the part with the objectName it disables the both of them)

if (((widget->inherits("QDockWidgetSeparator")) || (widget->inherits("QDockSeparator"))) && (widget->objectName()=="name"))
{
widget->setAttribute(Qt::WA_Disabled);
}

Could you maybe tell me how could I get from only a Qwidget his orientation : QStyle::State_Horizontal ????

Ok. let me be more clear:

I have a qmainwindow and in it 2 dockwidgets(left,bottom) and a qworkspace.
the problem is that the left one draws QDockSeparator on the right and on the bottom at his borders. I only want him to draw the QDockSeparator on the bottom border. How could I achieve this???

please help.

QDockSeparators are created/shown/hidden on the fly when needed. You cannot delete them or a crash will occur. You will have to monitor for every movement and possibly resize events too, and hide the separator again and again by hand when appropriate.

You can find the QDockSeparators like this:

// Notice this (from qdockseparator_p.h):
 
//
//  W A R N I N G
//  -------------
//
// This file is not part of the Qt API.  It exists purely as an
// implementation detail.  This header file may change from version to
// version without notice, or even be removed.
//
// We mean it.
//
#include <private/qdockseparator_p.h>
...
// notice that QDockSeparators are children of QMainWindow, not children of QDockWidget
foreach (QObject* obj, children())
{
	if (QString(obj->metaObject()->className()) == "QDockSeparator")
	{
		QDockSeparator* sep = qobject_cast<QDockSeparator*>(obj);
		if (sep && sep->orientation == Qt::Vertical)
		{
			...
		}
	}
}

foreach (QObject* obj, children())
{
	if (QString(obj->metaObject()->className()) == "QDockSeparator")
	{
		QDockSeparator* sep = qobject_cast<QDockSeparator*>(obj);
		if (sep && sep->orientation == Qt::Vertical)
		{
			...
		}
	}
}
