Aligning widgets within different composites [message #538607] Tue, 08 June 2010 08:03 Go to next message

Hello all

Say I have a form with 3 columns.

I want to group say the bottom two rows into an SWT Group widget.

How do I tell the bottom two rows that they have to have the same column
size as the columns above, when they belong to a different parent and have a
different gridlayout object?

Poorly drawn ASCII example:

x x
x x
x x
yy yy
yy yy

The y's are the grouped widgets. They have their own GridLayout (set on the
Group composite). I want the column width to be the same for both sets of
widgets, e.g

x x
x x
x x
yy yy
yy yy

Thanks!

Greg

explore griddata.horzontalspan and deduce it...

I think I have confused you with my ASCII art. The double y's indicate a
single widget. Therefore span doesn't help me here.

the double y represent a composite containing two buttons....

i understand that..now after seeing between the lines,the solution would be

package org.eclipse.swt.snippets;

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Group;
import org.eclipse.swt.widgets.Shell;

public class Snippet
{
    static Display display;

    static Shell shell;

    public static void main(String[] args)
    {
        display = new Display();
        shell = new Shell(display);
        shell.setSize(300, 300);
        shell.open();
        shell.setLayout(new GridLayout(5, true));
        for (int i = 0; i < 15; i++)
        {
            Button button = new Button(shell, SWT.PUSH);
            button.setText("B" + (i + 1));
            GridData layoutData = new GridData();
            layoutData.grabExcessHorizontalSpace = true;
            button.setLayoutData(layoutData);
        }
        Composite composite = new Group(shell, SWT.NONE);
        composite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
        composite.setLayout(new GridLayout(2, false));
        GridData layoutData = new GridData();

        Button button = new Button(composite, SWT.PUSH);
        button.setText("B16");
        Button button1 = new Button(composite, SWT.PUSH);
        button1.setText("B17");
        composite.setLayoutData(layoutData);

        Composite composite1 = new Group(shell, SWT.NONE);
        composite1.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
        composite1.setLayout(new GridLayout(2, false));
        GridData layoutData1 = new GridData();

        Button button11 = new Button(composite1, SWT.PUSH);
        button11.setText("B16");
        Button button12 = new Button(composite1, SWT.PUSH);
        button12.setText("B17");
        composite1.setLayoutData(layoutData);
        shell.layout();
        while (!shell.isDisposed())
        {
            if (!display.readAndDispatch()) display.sleep();
        }
        display.dispose();
    }
}


changing

GridData layoutData = new GridData();
layoutData.grabExcessHorizontalSpace = true;
button.setLayoutData(layoutData);

to

GridData layoutData = new GridData(GridData.FILL_HORIZONATL);
button.setLayoutData(layoutData);

also would be what u want...

You'll notice in this example the columns are aligned with the group, not
the button within the group.

I need to align the widgets (buttons in this example) in the groups, to the
widgets in another control (for example the parent composite, the section
above the groups in the example).

Here is a diagram of what I am trying to achieve:
y y
---------
| x x |
---------

The y's need to be aligned with the x's in the group.

Let me know if you do not understand the question.

ok now i got u r requirement

Quote:
package org.eclipse.swt.snippets;

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;

import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Group;
import org.eclipse.swt.widgets.Shell;

public class Snippet
{
static Display display;

static Shell shell;

public static void main(String[] args)
{
display = new Display();
shell = new Shell(display);
shell.setSize(300, 300);
shell.open();
shell.setLayout(new GridLayout(5, true));
GridData layoutData = new GridData(SWT.CENTER, SWT.TOP, true, false);
// layoutData.widthHint = 20;
for (int i = 0; i < 15; i++)
{
Button button = new Button(shell, SWT.PUSH);
button.setText("B" + (i + 1));

button.setLayoutData(layoutData);
}
GridData layoutData1 = new GridData(GridData.FILL_HORIZONTAL);
layoutData1.horizontalSpan = 2;
Composite composite = new Group(shell, SWT.NONE);
composite.setLayoutData(layoutData1);
GridLayout layout = new GridLayout(2, false);

layout.marginHeight = 0;
layout.marginWidth = 0;
composite.setLayout(layout);

Button button = new Button(composite, SWT.PUSH);
button.setText("B16");
button.setLayoutData(layoutData);
Button button1 = new Button(composite, SWT.PUSH);
button1.setText("B17");
button1.setLayoutData(layoutData);

Composite composite1 = new Group(shell, SWT.NONE);
composite1.setLayoutData(layoutData1);
composite1.setLayout(layout);

Button button11 = new Button(composite1, SWT.PUSH);
button11.setText("B16");
button11.setLayoutData(layoutData);
Button button12 = new Button(composite1, SWT.PUSH);
button12.setText("B17");
button12.setLayoutData(layoutData);
shell.layout();
while (!shell.isDisposed())
{
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
}



this is the closest it can get....

if u want a perfect dynamic match,i think it would not be possible...

by the way i am the same guy answering "Getting column width from GridLayout " query

thats why i told u forget that query concentrate on this one...
(i am just trying to help Smile )

Why not use either GridLayout or FormLayout and put them all in one
parent? multiple composites side-by-side are not a good solution for a
layout or alignment problem.

But I would like to use the SWT Group widget if possible. And the way I
understand it the Group becomes the parent composite of the controls.

It sounds like it is pretty much impossible.

Is there a way to reparent a subset of the widgets to a group afterwards,
and maintain the original alignment?

No, that doesn't work ... however ...

If you're willing to manage it you can manage your own layout for the
second group. If your first group is correctly laid out, you can use
button.setBounds(*) on your second set of buttons ... or use the Layout
protocol and actually write a Layout:

group1 ( button1 button2 )
group2 ( button3 button 4 )
group2.setLayout(new MyLayout(group1))

You would have to do the position calculations yourself, but you could
keep group2 in alignment with group1

IIRC MigLayout can position controls across composite borders. You can
install an OSGified version from
