Clearing the GUI

[November235]

Is there a way to clear all the elements I've added to an IGUIEnvironment in one command? As far as I can see, I have to keep pointers to all my elements and then remove them individually, which is something I'm not too keen on doing .

Meh. I guess storing them in a pointer array won't be that bad... there aren't that many .

Im not sure cause I'm new to IRR, but have you tried putting the element you want to clear into a IGUIWindow? (ie: create an IGUIWindow, and when you create those elements, set it as their parent)

When you delete the window, perhaps it clears it's children elements? Not sure..

You could get "getRootGUIElement()'s" Children from the Children list and removeChild() them.

[rt]

or you could add this function to IGUIElement.h

Code: Select all

	//! Removes All Children
	virtual void removeChildren() {
		// delete all children
		core::list<IGUIElement*>::Iterator it = Children.begin();
		while (it != Children.end()) {
			(*it)->Parent = 0;
			(*it)->drop();
			it = Children.erase(it);
		}
	}

then call

Code: Select all

void ClearGui() {
	irr::gui:: IGUIElement* ele = grr.env->getRootGUIElement();
	ele->removeChildren();
}
