resizing widgets when user resizes mainwindow

[Lykurg]

Use layouts, then you don't have to do the children resizing by your own: QLayout, QGridLayout...

EDITED

ive tried to lay my widget under a grid layout, for some strage reason the app compiled and run ok but i lost connection with my .cpp file, for ex i clicked on a button on my app and nothing happened! lol, when i removed the grid layout everything worked correctly again :P..

ive also tried to right click to my tabwidget and lay out as grid layout, but then i couldnt setup the widgets where i want them to be in the form.. lol...

so lets forget the layout method, i dont have a problem to code all of my widgets in the app to resize automatically as long as i know how to do it...

so please help hehe xD

Using QLayout correct don't break any functionality! Let me see some code and I might tell you the error... Just post it here.

hi and thx for the reply
well basically im doing all the form work using the QtCreator's intergrated designer, so i dont have a spesific laying out widgets code on my source file.

I could try to lay my widget in a QLayout using code if this is necessary (im trying to avoid setting up the widgets again via code coz it'll take ages you see )

oh!, i have some button that to be shown, they'll have to be triggered first not done with the designer and layeded out on a QVBoxLayout and QHBoxLayout, maybe thats why it breaks the functionality?

vbox = new QVBoxLayout;
     vbox->addWidget(pkgdesclbl);
     vbox->addWidget(pkgdescText);
     vbox->addWidget(pkgfilelistlbl);
     vbox->addWidget(pkgfilelistText);
     vbox->addWidget(consoleOutlbl);
     vbox->addWidget(consoleOutText);
 
     hbox = new QHBoxLayout(vbox);
     hbox->addWidget(pkgsaveBtn);
     hbox->addWidget(pkgcopyBtn);
 
     pkginfoBox->setLayout(vbox); //this is a QFrame in my applications form

vbox = new QVBoxLayout;
     vbox->addWidget(pkgdesclbl);
     vbox->addWidget(pkgdescText);
     vbox->addWidget(pkgfilelistlbl);
     vbox->addWidget(pkgfilelistText);
     vbox->addWidget(consoleOutlbl);
     vbox->addWidget(consoleOutText);

     hbox = new QHBoxLayout(vbox);
     hbox->addWidget(pkgsaveBtn);
     hbox->addWidget(pkgcopyBtn);

     pkginfoBox->setLayout(vbox); //this is a QFrame in my applications form

well i managed to lay out the tabwidget in my main window and when i resize the main window the tabwidget resizes along but not the widgets under the tabwidget.

i tried to lay out the widgets inside the tabwidget but as before it messes up my widget potitions and i cant set them in the way i want...

any help please?

any help please?

Sure. As soon as you post the code reproducing the problem or at least a screenshot of what you want to obtain.

[Mystical Groovy]

ok look, the problem is that i cant get the widgets inside tabwidget in my application resize along with the main window when the user resizes it.

first i tried to do this (as posted in the first post)

/* i suppose that when the user resizes the window, the height changes so i tried to check it with the following : */
if(!minimumSize().height == 800) //where 800 is the default height for the window
{
 tabwidget->updateGeometry();
// centralWidget->updateGeometry();
// setupUi(this);
}

/* i suppose that when the user resizes the window, the height changes so i tried to check it with the following : */
if(!minimumSize().height == 800) //where 800 is the default height for the window
{
 tabwidget->updateGeometry();
// centralWidget->updateGeometry();
// setupUi(this);
}

To copy to clipboard, switch view to plain text mode 

then Lykurg suggested to use layouts, but when i lay the widgets inside my tabwidget in a grid layout it messes the potition of the widgets up and i cant get them to where i want them to be shown.

That's why I ask you to post a screenshot (or better yet a ui file) and we'll help you place them in a layout. It's either that or doing the layout manually by reimplementing resizeEvent() of each and every tab in your window. It's really much quicker to do it with layouts.
