Problem with RowLayout wrap inside a FormLayout? [message #451458]

This seems very similar to an earlier post regarding a problem with
RowLayout wrap inside a GridLayout, but the same solution didn't work for
me because FormData does not have a widthHint.

Briefly, I have a composite which has a FormLayout. I want one component
of it to be a "button holder" composite with a rowLayout (horizontal), and
I want it to take up just enough room to hold its buttons, and that might
be one or two or three rows, depending on the width of the overall
composite. I want the other component of the composite to be the largest
size it can be (it's a drawing), taking up "the rest" of the room.

I attach the "button composite" to the left, top, and right of the
Composite holding it, and I attach the "picture" to the left, right, and
bottom of the Composite holding it, plus I attach its top to the
"buttonComposite". This does just what I want *except* that the "button
Composite" does not wrap; it clips the buttons instead, and remains one
row in height at all times.

As I mentioned, FormData does not have a widthHint, so I experimented with
using "width" instead like so (modifying the workaround given in the
earlier posting): however in this case, while it did wrap, the space it
takes up vertically did not change (that is, the "picture" did not get any
smaller, so it clipped off the buttons)

shell.addListener(SWT.Resize, new Listener() {
public void handleEvent(Event e) {
Rectangle area = shell.getClientArea();
FormData data = (FormData)(rightPanel.getLayoutData());
data.width = area.width;
shell.layout(true);
}
});

Is it possible to do what I want, that is, have the RowLayout "button
Composite" wrap properly?

What version of Eclipse/SWT are you running? In Eclipse 3.1 M3 or later =
the wrapping should just work without messing with the width value.

The following works for me in 3.0:

public static void main(String[] args) {
Display display =3D new Display();
final Shell shell =3D new Shell(display);
shell.setLayout(new FormLayout());
final Composite rightPanel =3D new Composite(shell, SWT.BORDER);
rightPanel.setLayout(new RowLayout());
for (int i =3D 0; i < 15; i++) {
Button b =3D new Button(rightPanel, SWT.PUSH);
b.setText("Button "+i);
}
FormData data =3D new FormData();
data.left =3D new FormAttachment(0, 10);
data.top =3D new FormAttachment(0, 10);
rightPanel.setLayoutData(data);
final Composite leftPanel =3D new Composite(shell, SWT.BORDER);
data =3D new FormData();
data.left =3D new FormAttachment(0, 10);
data.right =3D new FormAttachment(100, -10);
data.top =3D new FormAttachment(rightPanel, 10);
data.bottom =3D new FormAttachment(100, -10);
leftPanel.setLayoutData(data);
=20
shell.addListener(SWT.Resize, new Listener() {
public void handleEvent(Event e) {
Rectangle area =3D shell.getClientArea();=20
FormData data =3D (FormData)(rightPanel.getLayoutData());=20
data.width =3D area.width - 20;=20
shell.layout(true);=20
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}

The code above works in 3.1 but it can also be simplified to:

public static void main(String[] args) {
Display display =3D new Display();
final Shell shell =3D new Shell(display);
shell.setLayout(new FormLayout());
final Composite rightPanel =3D new Composite(shell, SWT.BORDER);
rightPanel.setLayout(new RowLayout());
for (int i =3D 0; i < 15; i++) {
Button b =3D new Button(rightPanel, SWT.PUSH);
b.setText("Button "+i);
}
FormData data =3D new FormData();
data.left =3D new FormAttachment(0, 10);
data.top =3D new FormAttachment(0, 10);
data.right =3D new FormAttachment(100, -10);
rightPanel.setLayoutData(data);
final Composite leftPanel =3D new Composite(shell, SWT.BORDER);
data =3D new FormData();
data.left =3D new FormAttachment(0, 10);
data.right =3D new FormAttachment(100, -10);
data.top =3D new FormAttachment(rightPanel, 10);
data.bottom =3D new FormAttachment(100, -10);
leftPanel.setLayoutData(data);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}

Thank you very much for your response. Unfortunately it has led to another
problem for me (hopefully with an easy fix).

I was using version 3.0, so I decided to upgrade to 3.1 to simplify
things. I downloaded the Windows SDK. Now when I start Eclipse (say by
just double-clicking on eclipse.exe in C:\eclipse) I get

JVM Terminated Exit Code=13

That doesn't sound good. Which version of Eclipse did you download? I =
would recommend 3.1 M5a. What VM are you using? It must be version =
1.4.1 or higher. Try downloading Eclipse again. Install in a clean =
place (i.e. not overtop of 3.0).

Thanks so much--
I had (stupidly) installed 3.1 over 3.0 and that caused all sorts of
problems. I reinstalled in a clean place, got the corresponding version of
GEF, updated my project properties so that the libraries point to the
newer jars for jface etc., updated my path to find the new swt dll and all
works as advertised. I noticed a need to resize my window to see my
widgets, but I recall something from this list about that so I'm not
worried and I'll go look it up and take care of it.

The rowlayout inside the formlayout does just what I expect now.

Thanks for your help; I have noticed that questions are quickly and
helpfully answered on this group list, even silly ones. It is really
appreciated :)
