disabling resizing of a dialog

[deepakn]

Hello all...

I have a dialog whose default size i have set [to some desired value]. After that, i want its resizing disabled. Could anyone please tell how to do that?

Here is a part of the code:

QVBoxLayout *mainLayout = new QVBoxLayout;
	mainLayout->addWidget(headerLabel);
	mainLayout->addWidget(onoffGbx());
.....
	mainLayout->addStretch();
	mainLayout->addLayout(buttonLayout);
 
	resize(380, 420); //here i have fixed the size. i want it to remain the same throughout.
	//mainLayout->setSizeConstraint(QLayout::SetFixedSize);
	setLayout(mainLayout);
 
	setWindowTitle("Testbed settings");

QVBoxLayout *mainLayout = new QVBoxLayout;
	mainLayout->addWidget(headerLabel);
	mainLayout->addWidget(onoffGbx());
.....
	mainLayout->addStretch();
	mainLayout->addLayout(buttonLayout);

	resize(380, 420); //here i have fixed the size. i want it to remain the same throughout.
	//mainLayout->setSizeConstraint(QLayout::SetFixedSize);
	setLayout(mainLayout);
	
	setWindowTitle("Testbed settings");

To copy to clipboard, switch view to plain text mode 

I tried mainLayout->setSizeConstraint(QLayout::SetFixedSize); but its changing the size to some default value of its own.

Also, by using mainLayout->addStretch(); can we fix the value of space[gap]? i saw mainLayout->addStretch(1); somewhere in the examples. Whats the significance of '1' there?

Thank you.

Hi,

Simply use setFixedSize( QSize(380, 420) );

It sets both minimum and maximum size in one call
