Changing the size of scrollbar [message #179419] Wed, 27 April 2005 09:40 Go to next message

Hi,

I have a figure which can content other figures inside it. This figure
has a scrollpane associated to it. The problem is that the figure has a
border that hides the half of the vertical and horizontal scroll bars. How
can I change the size of the scroll pane or the size of the scroll bars?

Thank you very much.

--Jose.

ScrollpaneLayout should handle borders already. Can you post some code?

Hello Randy, here you have the code:

...

public ComplexFigure() {
setBorder(new ComplexFigureBorder());
ScrollPane scrollpane = new ScrollPane();
pane = new FreeformLayer();
pane.setLayoutManager(new FreeformLayout());
setLayoutManager(new StackLayout());
add(scrollpane);
scrollpane.setViewport(new FreeformViewport());
scrollpane.setContents(pane);


setBackgroundColor(new Color(null, 230, 230, 230));
}
...

public class ComplexFigureBorder extends AbstractBorder {

...
public void paint(IFigure figure, Graphics g, Insets in) {
Rectangle r = figure.getBounds().getCropped(in);

g.setForegroundColor(new Color(null, 222, 220, 122));
g.setBackgroundColor(new Color(null, 222, 220, 122));

//Se dibuja el borde grueso
g.fillRectangle(r.x, r.y+2, r.width, 12);
g.fillRectangle(r.x, r.bottom() - 14, r.width, 12);
g.fillRectangle(r.x, r.y + 2, 12, r.height - 4);
g.fillRectangle(r.right() - 12, r.y + 2, 12, r.height - 4);

}
...
}


Can you help me?

Thank you very much.

--Jose.

Your border doesn't have any insets. How will the layout mangaer's know how
much space to reserve?
