C++ (Cpp) Button::GetNextRadio Examples

Example #1

File: Button.cpp Project: SOLARIC/world-opponent-network

void Button::AddedToParent()
{
	Component::AddedToParent();
	SetButtonFlags(ButtonFlag_ButtonDown | ButtonFlag_MouseOver,false);

	// Make sure all of the focus issues with the radio buttons are handled.
	// A checked radio wants the focus, and an unchecked radio doesn't want
	// the focus.  However, if no radio in the group is checked then one of
	// the radios should still want the focus.
	if(IsRadio())
	{
		SetCheck(IsChecked());
		bool aRadioWantsFocus = false;
		if(!WantFocus())
		{
			Button *aRadio = GetEndRadio(false);				
			while(aRadio!=NULL)
			{
				if(aRadio->WantFocus())
				{
					aRadioWantsFocus = true;
					break;
				}
				
				aRadio = aRadio->GetNextRadio(true);
			}
			
			if(!aRadioWantsFocus)
				SetComponentFlags(ComponentFlag_WantFocus,true);
		}
	}
