Hi,

I have some problems with the ToolbarLayoutManager.
I need a layoutmanager, who handles three figures, alinged in a row or
column (configurable).
I explain the problem now with horizontal alignment:

The left and the right figure have to have the height of the center
figure, which serves as a
container for the childFigures.
The left and right figures just paint some lines, which depends from the
size of the figure (i.e. drawLine from top to bottom)
The problem is, that when i use a normal ToolbarLayout (or
BorderLayout), the outer figures have the standard size of (64,36) and
are smaller than the center figure. But they should have the same height
as the centerFigure (width of 64 is ok).
So i overwrote the layout()-method of the toolbarLayout like this:

Rectangle badBoundsLeft =((IFigure) children.get(0)).getBounds();
Rectangle badBoundsRight =((IFigure) children.get(2)).getBounds();
Rectangle centerBounds ==((IFigure) children.get(1)).getBounds();
((Figure) children.get(0)).setBounds(new Rectangle(badBoundsLeft.x,
badBoundsLeft.y, badBoundsLeft.width, centerBounds.height));
((Figure) children.get(2)).setBounds(new Rectangle(badBoundsRight.x,
badBoundsRight.y, badBoundsRight.width, centerBounds.height));

and (another try) like this

badBoundsLeft.height = centerBounds.height;
badBoundsRight.height = centerBounds.height;

Now everything is drawn fine. But the child figures can be collapsed and
expanded (works fine). The problem is, that with collapsing the height
and the width changes. With the above changed layoutManger, the height
isn

Without looking at what your post is really about, it seems you missed the
method ToolbarLayout#setStretchMinorAxis

No, i didn´t. I don´t want to let the height of the middle figure grow,
i want the other figures be shrinked to the height of the middle figure.

In that case, if those figures returned a preferred height of 1 pixel, they
would be stretched vertically to the central figure's height.

That nearly works (it was 50% of the solution). But because the
layoutmanager touches and calculates the figure heights from the left to
right figure (normal iteration), the left figure has the old height of
the center figure. So the whole figure is too tall, but the center
figure will be arranged correctly.

My solution is to overwrite the ToolbarLayout#layout(IFigure) method,
and at first store the new calculated bounds in a variable, changing the
heights to the center figure´s height and then setting the bounds to the
figures.

Now everything is shown correctly...
Thank you VERY much... :-)

Andreas

PS: I´m still interested why setting the bounds manually does not work
properly...?

You should be using a Border perhaps.
