Launch a QWidget from a QMain window
- by Opera
Hello everyone !
I'm doing my first C++ - Qt4 application and I'm having some trouble "connecting" my different uis.
I have a main window with several buttons and when I click on one, I want another window to open.
The MyMainWindowClass inherits from QMainWindow and the other from QWidget.
Here is the code I have written so far :
#include <iostream
#include "MyWidgetClass.hpp"
#include "MyMainWindowClass.hpp"
#include "ui_MyMainWindowClassUi.h"
MyMainWindowClass::MyMainWindowClass(QWidget *parent) :
QMainWindow(parent),
m_ui(new Ui::MyMainWindowClassUi)
{
m_ui-setupUi(this);
initConnect();
}
void MyMainWindowClass::initConnect()
{
QObject::connect(m_ui-SomeBtn,
SIGNAL(clicked()),
this,
SLOT(SomeBtnClicked()));
// Some other QObject::connect calls
return;
}
void MyMainWindowClass::SomeBtnClicked()
{
std::cout << "Some Btn has been clicked" << std::endl;
this-setEnabled(false);
MyWidgetClass mwc(this);
mwc.show();
return;
}
This calls the Ctor and the Dtor from MyWidgetClass, disables the MyMainWindowClassUi, but doesn't show my other GUI. What am I missing to have the window showed when I click on the button ?
