As can be seen with the following example : it is impossible to grab the resize handle :

#include <QtGui>

class TestDialog : public QDialog
{
public:
TestDialog()

{ setSizeGripEnabled(true); QGridLayout* gl = new QGridLayout(this); //setting a small margin results in the resize grip being unavailable: //gl->setMargin(5); gl->setSpacing(5); QPushButton* okButton = new QPushButton("OK"); connect(okButton, SIGNAL(clicked()), this, SLOT(accept())); gl->addWidget(okButton,1,2); }

};

int main(int argc, char **argv)
{
QApplication app(argc, argv);
TestDialog td;
return td.exec();
}
