c++ - Disable resizing of a form -

i want disable resizing form - here have tried. have changed resize policy of form following horizontalpolicy:fixed verticalploicy: fixed

i have tried following

form *w = new form();  w->setfixedsize(w->size()); w->show(); 

but form still gets resized dragging corners. suggestions ?

it has possible.

firstly should know, before window shown has no information of it's size - size return 0 (or invalid; or ;) ) @ point - mess entire sizing , therefore silently rejected. try

form *w = new form(); //w->ensurepolished(); w->setfixedsize(w->sizehint()); w->show(); 

size hint should have correct value no matter what. qwidget::ensurepolished() might necessary here, recommend trying first without - if works, why complicate things?

if still doesn't work, can try overriding resizeevent() , setting the right size widget if user resizes else. still give user illusion of resize-ability (cursors changes on edges , on), it's last option.

edit:

#include <qtgui/qapplication> #include <qwidget>  int main(int argc, char *argv[]) {     qapplication a(argc, argv);     qwidget w;     w.setfixedsize(500,500);     w.show();     return a.exec(); } 

result: widget cannot resized. not change qmainwindow helped - oat least on system simple widget can ;)
