Window doesn't expand to show all elements of QHBoxLayout

I'm building a tic-tac-toe game.

In my main window, I've got a QHBoxLayout holding the board (UIBoard), and the settings (which now consist of a start and quit button). uiSettings uses a QGroupBox and a QVBoxLayout in order to hold the start and quit buttons.

Everything works, but when I start the program, I have to manually enlarge the window so that everything is shown -- not just the board.

Here's the code:

uiMain.hpp

Code:

---

#ifndef UIMAIN_HPP_
#define UIMAIN_HPP_
 
#include <QPushButton>
#include <QHBoxLayout>
#include <QVBoxLayout>
#include <QApplication>
 
#include "uiBoard.hpp"
#include "uiSettings.hpp"
 
namespace ttt {
	class UIMain : public QWidget {
		Q_OBJECT
		private:
			UIBoard *uiboard_;
			UISettings *uisettings_;
			QHBoxLayout *mainLayout_;
		public:
			UIMain();
	};
}	
 
#endif /*UIMAIN_HPP_*/

---

uiMain.cpp

Code:

---

#include "uiMain.hpp"
 
namespace ttt {
	UIMain::UIMain() :
		QWidget(),
		uiboard_( new UIBoard( 'X', true, this ) ),
		uisettings_( new UISettings( this ) ),
		mainLayout_( new QHBoxLayout( this ) ) {
 
		uiboard_->setFixedSize( 300, 300 );
 
		mainLayout_->addWidget( uiboard_ );
		mainLayout_->addWidget( uisettings_ );
	}
}

---

And finally, main.cpp

Code:

---

#include <iostream>
 
#include <QApplication>
 
#include "uiMain.hpp"
 
int main( int argc, char *argv[] ) {
	QApplication app( argc, argv );
 
	ttt::UIMain game;
	game.show();
 
	return app.exec();
}

I've attached images showing what I see when I start the program, and what I see after I manually enlarge the window.

Any help would be greatly appreciated and I'd be happy to provide more information if it would help. :)

Add this line at the end of your constructor:

Code:

---

setFixedSize(sizeHint());

---

EDIT: or if you don't want a fixed size for the window, try:

Code:

---

resize(sizeHint());

---

When I try either of those in the UIMain() contructor, the board is still the only thing shown.

EDIT: I should mention that I'm able to resize so that some elements are only half-visible (like in the attached image). Maybe it's a clue to the problem? :confused:



Any other ideas (but thanks anyway :)) ?

It looks as if the widget does not have a layout set.

Could you try adding this as the last line in the constructor?

Code:

---

setLayout(mainLayout_);

---

If this alone does not work, see what happens if you subclass QDialog instead of QWidget.
Just replace QWidget with QDialog in the class declaration and in the constructor initialization list.

EDIT: it could be a problem with the fact that you're using "this" in the constructor initializer list. I am not sure if all compiler handle that well. Do you get any compile time warnings about that?

Regards

I don't know what to tell you, marcel. :(

I've inherited UIMain from QDialog and

Code:

---

setLayout( mainLayout_);

---

And it still defaults to just showing the board.

Maybe I could set the minimum size?

In any case, thanks for the continued help. :)

Weird.
Maybe if you can provide a compilable example it would be easier to spot the problem.

There's no need for minimum size. Setting the fixed size should have done it.

Sorry marcel, but the game and the GUI are pretty entwined.
I'm releasing this under the GPL anyways (I'm just a hobbyst :)) so I'm happy to just post the sources.

The files that are problems here are uiSettings.[hpp, cpp] uiMain.[hpp, cpp] and main.cpp.

OK.
I have to download boost first.

Shouldn't take more than 30-45 minutes with the whole testing.

Oy :eek:.

This is highly appreciated. :o

EDIT: Take all the time you need. I'm in no hurry.

OK.
There was a problem in UISettings. You did not have a layout for the holder widget( the container of the group box ).

Here's the fixed version:

    }

I also set a fixed size for the dialog, since the table does have a fixed size.(i did not attach that )

That's fantastic! Thanks so much. :)

You're welcome.
