Qt sloty problem s dynamickou alokaci – C / C++ – Fórum – Programujte.com

ahoj,mensi problem,ve tride mam 5 dynamicky vytvorenych tlacitek v konstruktoru a kdyz stisknu tlacitko nejake tak k nim chci ve slotu pristupovat,ale vyhodi to chybu jako by pamet vubec nebyla alokovana. 

gui.cpp: 

gui::gui (mujserver * server)
{
	QLabel * popisekAdresa=new QLabel ("adresa");
	QLabel * popisekPort=new QLabel ("port");
	QLabel * popisekZprava=new QLabel ("zprava");

	connect (startServer,SIGNAL (clicked ()),this,SLOT (start()));
	connect (stopServer,SIGNAL (clicked ()),this,SLOT (stop()));

gui.h

#endif GUI

poradte prosim cim to je,uz si s tim nevim rady. vzdyt pamet sem prece alokoval.

#1 rodinne.baleni.ryze
udělej ty tlačítka jako privátní atributy třídy gui.

pak v konstruktoru alokuj:

class gui {
	Q_OBJECT
private:
	QPushButton *prvni;
	...
};

gui::gui() {
	prvni = new QPushButton(this);
	...
	connect(prvni, SIGNAL(clicked),
		this, SLOT(...));
	...
}

a kde vůbec vytváříš ty layouty?

tak vytvarim,nebo sem si aspon myslel ze je vytvarim tady. 
v hlavickovem:
QPushButton * kickClient,*kickAllClients,*sendMsg,*startServer,*stopServer,*nastavit;
a ve zdrojovem kodu
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");
QPushButton * nastavit=new QPushButton ("nastavit");
a ja je jako privatni atributy uz mam nebo to delam spatne? asi delam.dekuju za radu jeste se nato podivam

pomozte prosim :( vubec si s tim nevim rady. prece je vytvarim spravne ne? mam to stejne jako ty

moc dekuju uz to vidim,uplne sem to prehledl. dekuju za pomoc
