QMdiSubWindow
Message 1 in thread
Friends,I have an application in MDI and the new version of the QT (4.3.0)
will start to use new class, as QMdiArea and QMdiSubWindow.To place a window inside of the workspace a special window is created that
controls the embebed content. However in some tests the slot “close( )”
of the button eliminates the content all, but not destroy the window
that controls (QMdiSubWindow).In
the embebed Window I fixed the dimensions, however this does not
function in activity with QMdiSubWindow. Its follow part of the code:AlterPass *MainWindow::createAlterPass( ){ AlterPass *win = new AlterPass; QMdiSubWindow *currentWindow = new QMdiSubWindow; currentWindow->setWidget(win); currentWindow->setAttribute(Qt::WA_DeleteOnClose); mdiArea->addSubWindow(currentWindow); currentWindow->show();}Thanks,Marcelo Estanislau.

This behavior is the same for all widgets in Qt. Deleting a child widget
will not delete its parent widget, closing a child widget will not close
its parent widget etc.
Use QMdiSubWindow::close if you want to close the sub-window itself.

How I can write of clear form this? I have MainWindow and AlterPass (drawn in Qt Designer).The problem is that I'm not obtaining to pass the control of the parent widget for inside of the child widget (AlterPass class), making possible to
close the parent widget.Follow part of the code:----- MainWindow.cpp -----AlterPass *MainWindow::createAlterPass( ){ AlterPass *win = new AlterPass; QMdiSubWindow *currentWindow = new QMdiSubWindow; currentWindow->setWidget(win); currentWindow->setAttribute(Qt::WA_DeleteOnClose); mdiArea->addSubWindow(currentWindow); currentWindow->show();}---- End of MainWindow-------- AlterPass.cpp----AlterPass::AlterPass(QWidget *parent) :QWidget(parent){ ui.setupUi(this); move(0,0);}AlterPass::~AlterPass( ){ }void AlterPass::closeEvent(QCloseEvent *event){ event->accept();}---- End of AlterPass----Thanks,Marcelo EstanislauStandard Net Tecnologia e Informação.> -- > Bjoern Erik Nilsen - bnilsen at trolltech.com> Trolltech ASA - Sandakervn. 116, P.O.
