close() and show()->newwindow problem

[danoc93]

I'm using this on my program to call new windows, but there is a problem... I close the actual window and call a new one. It works, but the icon on the task bar vanishes so my application is "floating" on the desktop , what could be happening?

Please describe your problem better. Possibly with a piece of code or a screenshot.

MM ok...

I have 2 classes...

Window1.h
Window1.cpp

Window2.h
Window2.cpp

The program starts and Window1 shows up just fine...

Then using this code

in Window1.h
#include Window2.h

public slots:
void openwindow2();

private:
Window2 * window2win;

private slots:
void on_button_clicked();

in Window1.cpp

void Window1:n_button_clicked(){

openwindow2();

}

void Window1:penwindow2(){

close(); //closes current window
window2win = new Window2 (this);
window2->show(); //shows the new window but it doesn't appear on task bar...

}


Look:

I click on "codigos de ejemplo" and the new window shows up but the icon dissapears once the previous window closes... lol...

Only parent-less QWidgets become windows, and only top-level windows get a task bar presence. Make window2 parent-less and then worry about memory deallocation (Qt::WA_DeleteOnClose).

And have you thought about using QStackedWidget? Thus you don't have to close() and hide() your windows and can stay with one main window.
