Hello friends, now I try to locate my error in my logic.

here are a piece of my app:

To copy to clipboard, switch view to plain text mode 

when I run newOrderSpace() my tableview fills with Item and when I click on them getProjectItem() runs. And I get my Qwidget AktProjektMaske.

The Problem now when I run newOrderSpace n times I get n QWidgets when I click on my Item on Tableview.
Whats wrong here friends??

P.S.: MdlProjektErstellung is a Widget in my QStackedWidget from Mainwindow.....

[Lykurg]

Use a member variable for MdlProjektMaske and reuse it or use the widget attribute Qt::WA_DeleteOnClose. But why are you using a widget and no dialog? where is MdlProjektMaske shown?

[codeman]

In the Contructor of MdlProjektMaske I still use

this->setAttribute(Qt::WA_DeleteOnClose);

this->setAttribute(Qt::WA_DeleteOnClose);

To copy to clipboard, switch view to plain text mode 

but nothing changes. I also try to replace QWidget with QDilaog same result multiple widgets there seemss to be a knowledge gap by me..

but where to go..

[codeman]

Ok now I implement a Dialog class as member and use it in my func like this

//**************************************************************************
void MdlProjektErstellung::GetProjectItem(const QModelIndex& index)
//**************************************************************************
{
 
 
this->setAttribute(Qt::WA_DeleteOnClose,true);
this->mymask->exec();
}

//**************************************************************************
void MdlProjektErstellung::GetProjectItem(const QModelIndex& index)
//**************************************************************************
{


this->setAttribute(Qt::WA_DeleteOnClose,true);
this->mymask->exec();
}

To copy to clipboard, switch view to plain text mode 

same thing I get n Dialogs after I clode the one it pop up a new dialog

[JohannesMunk]

The problem is that the connect-statement is executed n times. Then every time the signal is emitted the slot is called n times..Thats why you get n dialogs. You need to set this up in a constructor!

HIH

[codeman]

And this one also gets multiple Dialogs

//**************************************************************************
void MdlProjektErstellung::GetProjectItem(const QModelIndex& index)
//**************************************************************************
{
QString str;
str=tableModel->data(index,0).toString();
 
this->mymask       = new dlgPrjMaske;
this->mymask->setAttribute(Qt::WA_DeleteOnClose,true);
this->mymask->exec();
}

//**************************************************************************
void MdlProjektErstellung::GetProjectItem(const QModelIndex& index)
//**************************************************************************
{
QString str;
str=tableModel->data(index,0).toString();

this->mymask       = new dlgPrjMaske;
this->mymask->setAttribute(Qt::WA_DeleteOnClose,true);
this->mymask->exec();
}

To copy to clipboard, switch view to plain text mode

@ Johannes Munk Thank You very very very much I take the next best wall Ohhh mannnn How could I overlook...

really thank youu

[JohannesMunk]

Glad to be of assistance!

And: Skip the wall! This exact same thing, happened to me once, too.. We only learn from our mistakes..
