qt - QDialogs using layouts but with a fixed size (no size grip) -

i have several qdialogs have made in qt designer use layouts, dialog can size correctly depending on size of children. size of children run-time dependent (variable text fields, system font size etc).

it not make sense dialog user-resizeable, want size grip disabled. far can tell, size grip disabled calling setfixedsize(). however, cannot put in pixel size here, have implemented resizeevent() so:

void cremoteconnectiondialog::resizeevent(qresizeevent *) {     setfixedsize(minimumsize()); } 

this works fine on windows, dialog far small on mac os x.

how can achieve program resizable not user resizeable qdialog takes minimum space requires based on run-time state?

try on dialog:

this->layout()->setsizeconstraint(qlayout::setfixedsize);
