Timing of calling "Draw" function

Ashley

Here is the description of timing of calling "Draw" function (reference)

"Called when Construct wants the instance to draw itself in the Layout View."

I am curious when to call this draw function by IDE. (perhaps each tick?)

The use-case is, I have a property to set to color of placeholder. Here is the code to draw that placeholder.

		Draw(iRenderer, iDrawParams)
		{
			// render placeholder
			iRenderer.SetAlphaBlend();
			iRenderer.SetColorFillMode();
			iRenderer.SetColor(this._inst.GetPropertyValue("color"));
			iRenderer.Quad(this._inst.GetQuad());
		}

The color of placeholder is changed when I set that "color" property. It worked great. 
But... I had not added code under "OnPropertyChanged" function. Supposing that I should invoke redrawing with new color under "OnPropertyChanged" function.

Draw() is called when the layout view renders, which is usually one-off when something has changed, but can be every tick (e.g. if drag-scrolling).

The layout view automatically redraws when any property changes, so your code will work without having to add anything in OnPropertyChanged.
