Hi
Nope. When you use promotion, Creator adds the needed included. You tell it what file
in the promotion dialog. ( look at image)

---

and after you promoted it.
Then right click outside the widget and add a layout so our widget follow size of dialog automatically

[AliM93]

@mrjj ok so i click Promote and that's all

[mrjj]

@AliM93
Yes click promote now. as you have added info.
I hope you spelled right :)

[AliM93]

@mrjj done! also the layout

[mrjj]

@AliM93
Ok then we need button to show dialog.
so add button
Right click it and goto slot.
Choose Released
Add the code. ( want me to show that ?)

[AliM93]

we need to add thi button to the main_window?

[mrjj]

@AliM93
Where ever you want to open it from.
Main win sounds good.

#include "GridDialog.h"

void MainWindow::on_pushButton_released()
{
    GridDialog dia; 
    dia.exec();
}

[AliM93]

@mrjj which is the difference between released and clicked? (curiosity)

Done.

[mrjj]

@AliM93
Clicked = triggers when you click
Release = triggers when you release the left mouse button.
You can use any of them.

[mrjj]

Ok
super.
Now run it and click button :)
I hope it shows something.

[AliM93]

thank, only one thimg, i get error with your code, i can use Griddialog = new griddialog(this);
griddialog ->show();

[mrjj]

@AliM93

Mind the case

Griddialog = new griddialog(this); <<< that is not correct class name and u missed * and name

GridDialog * dia = new GridDialog (this);

GridDialog <<< class name

[AliM93]

i get error, i have something to declare in main_window.h?

[mrjj]

@AliM93
well you must have the GridDialog.h include file

[AliM93]

ii've done that

[mrjj]

@AliM93
Then you must have missspelled something as that is all you need.
Show excact code and the error
