Customizable ShapeCompartmentEditPart [message #202601]

Hello,

I need a ShapeCompartmentEditPart which I can customize dynamically when
the size changes. For example I need the compartment to be resized with
a specific size when the parent symbol is resized. In another more
expressive words, I need a compartment in the middle of a rounded
rectangle so that when I resize this rectangle vertically the
compartment should be stretched vertically too.

I tried all refresh() methods of the parent and the
ShapeCompartmentEditPart child with no success. Currently I use
ConstrainedToolbarLayout layout manager for the rounded rectangle.
Should I create my own layout manager or there is a simpler solution for
my ordinary case?

Thanks in advance,
Kalin

Hi,

Yes, there is a way not to override the layout manager. Override
#getClientArea() on your rounded rectangle figure (compartment's parent).
Return the rectangle where your shape compartment needs to be. Don't
forget that figure's client area must be contained within the bounds of
the figure.
Hope this helps.

Cheers,
Alex

I meant that if you express the client area rectangle in terms of your
bounds rectangle, the compartment will grow in size as bounds of the
figure grow in size. Rectangle#shrink(int h, int v) should do the client
area rectangle for trick for you.
Examples:
public Rectangle getClientArea(Rectangle rect) {
Rectangle area = super.getClientArea(rect);
area.shrink(area.width / 4 , area.height / 4);
return area;
}

or
public Rectangle getClientArea(Rectangle rect) {
IMapMode mm = MapModeUtil.getMapMode(this);
Rectangle area = super.getClientArea(rect);
area.shrink(mm.DPtoLP(5) , mm.DPtoLP(5));
return area;
}

Cheers,
Alex
