Qt setlayout segmentation fault – C / C++ – Fórum – Programujte.com

Ahoj,soucasti meho serveru v QT je jednoduche gui,prvky jsou dany do horizontalniho  layoutu,obsah kazdeho layoutu se vlozi na samostatny widget ,ty se pridaji do vertikalniho layoutu a ten se nasledne nestavi jako hlavni layout pro cele okno. vysledkem je okno co ma 2 polozky vertikalne a 5 horizontalne. proc do jde jenom tak slozite netusim. ale k problemu.. ono to nefunguje. vsechno funguje jak ma,vytvorim polozky,vlozim do layoutu ale pri pokusu dat obsah layoutu na widget ( aby byl samostatny widget na jeden radek) to spadne. prikladam kod.

 gui.cpp :

#include "gui.h"
gui::gui ()
{
	QPushButton * kickClient=new QPushButton ("vykopnout klienta");
	QPushButton *kickAllClients=new QPushButton ("vykopnout vsechny klienty");
	QPushButton *sendMsg=new QPushButton ("posli zpravu");
	QPushButton *startServer=new QPushButton ("nastartovat");
	QPushButton *stopServer=new QPushButton ("stop");
	QHBoxLayout *layout=new QHBoxLayout ();
	QHBoxLayout * layout2=new QHBoxLayout ();
	QVBoxLayout * Vlayout=new QVBoxLayout ();
	QComboBox * listClients=new QComboBox ();
	QLineEdit * adresaEdit=new QLineEdit ();
	QLineEdit *portEdit=new QLineEdit ();
	QWidget * widget=new QWidget (this);
	QWidget * widget2=new QWidget (this);
	widget->show ();
	layout->addWidget (kickClient);
	layout->addWidget (kickAllClients);
	layout->addWidget (sendMsg);
	layout->addWidget (startServer);
	layout->addWidget (stopServer);
	layout->addWidget (listClients);
	layout2->addWidget (adresaEdit);
	layout2->addWidget (portEdit);
	layout2->addWidget (nastavit);
	widget->setLayout (layout);
	widget2->setLayout (layout2);
	Vlayout->addWidget (widget);
	Vlayout->addWidget (widget2);
	this->setLayout (Vlayout);
	show ();
}
