[fixed][gui artifact] Combo box

[REDDemon]

There is a little gui artifact that appens when you use combo boxes that have 4/6+ items.

When number of items is greater than a certain value a ScrollBar is added to the combobox so you can scroll all items, if you scroll the Combobox using the ScrollBar or the Mouse Wheel, the highlight of the item lose its focus and it stops updating.

You can always click and select the right item, but while you are doing that the "blue highlight" still remains in the last place it was before you have clicked the scroll bar.

That's nothing really important anyway.

Bug was sitting a few stages deeper in the scrollbar which did eat all mouse-move events when it had the focus. I've changed it in 1.7 branch in revision 3645 so that mouse-move-events are now passed on to the parent of the scrollbar (the listbox in this case) when it doesn't need them itself.

Test-code:

Code: Select all

#include <irrlicht.h>

#include <iostream>



using namespace irr;

using namespace core;

using namespace scene;

using namespace video;

using namespace io;

using namespace gui;



#ifdef _IRR_WINDOWS_

#pragma comment(lib, "Irrlicht.lib")

#endif





int main()

{

	video::E_DRIVER_TYPE driverType = video::EDT_OPENGL;

	IrrlichtDevice * device = createDevice(driverType, core::dimension2d<u32>(640, 480));

	if (device == 0)

		return 1; // could not create selected driver.



	video::IVideoDriver* driver = device->getVideoDriver();

	IGUIEnvironment* env = device->getGUIEnvironment();



	core::rect<s32> rect(10, 10, 200, 30);

	IGUIComboBox * combo = env->addComboBox (rect, 0, /*s32 id=*/-1);

	for ( int i = 0; i < 6; ++i)

	{

		core::stringw wstr(i);

		wstr += L"Alpha";

		combo->addItem(wstr.c_str());

		wstr += L"-Beta";

		combo->addItem(wstr.c_str());

	}



	while(device->run() && driver)

	{

		if (device->isWindowActive())

		{

			driver->beginScene(true, true, SColor(0,200,200,200));



			env->drawAll();



			driver->endScene();

		}

	}



	device->drop();



	return 0;

}

Thanks for reporting.
