[solved] How to get a real size of received and maximized window.

[never_ever]

Hi,
I have a method that get pointer to widget where should be setted some other widgets. I have to resize the main window, where that widget is placed and then I should get the real size of that widget.

I've tried to do this like:

@
void MyClass::setWidgets(QList<QWidget*> list, QWidget parentWidget)
{
QWidget mainWindow = parentWidget->window();
mainWindow->showMaximized();

int width = parentWidget->size().width();
int height = parentWidget->size().height();
/*... rest of method...*/

}
@

That method is call from other class.
But I read that I should wait for resizeEvent. Could anyone explain me how I should do this or if there is any option to get that size differently?

Hi,

What are you trying to achieve exactly with setWidgets ?

I wanted to add QWidgets to the window. I managed that problem with some help from other forum. Writing resizing filter was enough.

This is what I found ("link here - code also below":http://stackoverflow.com/questions/24203215/qt-how-to-get-real-size-of-maximized-window-that-i-have-pointer-to/24205602#24205602

bq.
If you want to get events for a different object, you can install an event filter using QObject::installEventFilter.
bq.
A simple example for ResizeEvent is:

filter.h

@
#ifndef FILTER_HPP
#define FILTER_HPP

#include <QtGui>

class ResizeFilter : public QObject
{
Q_OBJECT
public:
ResizeFilter();
protected:
bool eventFilter(QObject *obj, QEvent *event);
};

#endif
@

filter.cpp

@
#include "filter.h"

ResizeFilter::ResizeFilter() : QObject() {}

bool ResizeFilter::eventFilter(QObject obj, QEvent event)
{
if (event->type() == QEvent::Resize)
{
QResizeEvent resizeEv = static_cast<QResizeEvent>(event);
qDebug() << resizeEv->size();
}
return QObject::eventFilter(obj, event);
}
@

main.cpp

@
#include <QtGui>
#include "filter.hpp"

int main(int argc, char** argv)
{
QApplication app(argc, argv);

ResizeFilter filter;

QWidget window;
window.installEventFilter(&filter);
window.showMaximized();

return app.exec();
}
