I'm making a shape editor. When I choose the circle button if I press the mouse button it appears a circle in the form, if I choose the square button it appears a square in the form.
But I have to do an MDI Application with this. When I want to put the OnMouseDown event it doesn't work. When it's only one Normal form it works fine, but when it is a MDI form with its child form it doesn't work.
Could you tell me what is the secret to appear the shapes in the form?
If I do this with a TImage it doesn't work also with MDIform and child.
What OnMouseDown event I have to use, the father of the child?
