MigLayout component dynamic sizing question

[pbl...@hotmail.com]

Hi

I have a node that I want to put into "south" of a docking Mig
layout. I want the node to have a fixed height and width vary with
resizing. The control needs to know what its present width is.

In MyControl I watch for sizing :

public class MyControl extends CustomNode, Resizable {
var windowWidth: Number = bind width on replace {
System.out.print("myctl ww ");
System.out.print(width);
System.out.print(" h ");
System.out.println(height);
}
var windowHeight: Number = bind height on replace {
System.out.print("myctl wh ");
System.out.print(height);
}
...
}

When I insert my node I use :

MigLayout {
layout: "fill"
migContent: [
MigNode {
constraints: "grow"
node: MyControl {
height: CONSTANT_HEIGHT
}
}
]
}

When I resize the window I see the expected width, but height is never
set/modified. I print it in windowWidth and it's always 0 (and I
never see my node).

I have never used MigLayout before and I must be missing something
obvious. I would greatly appreciate any pointers.

Thanks

Peter,

What is MyControl returning for min/pref/max height?

Tip for easier printing: there is no need to qualify with System.out and you can use embedded string expressions.

  println( "myctl ww {width} h {height}" );

I just looked through the javadoc for CustomNode and Node, and I don't
see any way to "return" those dimensions. I do see that a Node has a
boundsIn{Local|Parent|Scene}. I have not tried to set these. I
assume boundsInLocal is the one I want. I will give it a try, but in
the mean time if that's not what you meant then feel free to comment.

Thanks & Regards
Peter

Peter,

If a node is Resizable (check the javafx.scene.layout package) then it will have a min/pref/max width and height.  MigLayout will use those values to size the node.  If it is not Resizable, then MigLayout will only position the node, not size it.
