Hi all,
I'm getting crazy with layouts in RAP, I've made a lot of changes in
code but without success, I looked at all examples but today isn't a
good day :-( I didn't find anything that can help me.
I've attached a Screenshot of "my problem", that is, the Shell and its
components such as appear in the browser, are all too near among them, I
can't understand what is happening, It's possible I making somethiing
wrong but I don't see what.
Please, HELP :-)
Thanks in advance.
Regards.
Roberto.
PD: This is my code (In the attached image the result of this code):
public class LoginShell extends Shell {
public LoginShell(Shell parent) {
super(parent, RWT.NONE | RWT.APPLICATION_MODAL | RWT.SHELL_TRIM
| RWT.RESIZE );
this.setSize( 400, 500 );
this.createShellContent();
this.setImage(Image.find( "icons/logo-am16x16.png",
this.getClass().getClassLoader() ));
}
private void createShellContent() {
final Composite content = new Composite( this, RWT.NONE);
Rectangle ca = this.getClientArea();
content.setBounds( ca.x, ca.y, ca.width, ca.height );
content.setBackground(Color.getColor(new RGB(0xFC, 0xFC, 0xCC)));
// Setting layout
RowLayout rowLayout = new RowLayout(RWT.VERTICAL);
/* rowLayout.wrap = false;
rowLayout.pack = true;
rowLayout.justify = false;
rowLayout.type = ;
rowLayout.marginLeft = 5;
rowLayout.marginTop = 5;
rowLayout.marginRight = 5;
rowLayout.marginBottom = 5;
rowLayout.spacing = 5;
*/
content.setLayout(rowLayout);
// Logo
Label image = new Label(content, RWT.NONE);
image.setImage(Image.find("icons/logo-autonomind.png",
this.getClass().getClassLoader()));
// Group for email / password
Group datos = new Group(content, RWT.NONE);
datos.setText("Login Data");
datos.setLayout(new GridLayout(2, false));
Label userNameLabel = new Label(datos, RWT.NONE);
userNameLabel.setText("E-Mail:");
Text userName = new Text(datos, RWT.FLAT | RWT.BORDER);
Label userPasswordLabel = new Label(datos, RWT.NONE);
userPasswordLabel.setText("Password:");
Text userPassword = new Text(datos, RWT.FLAT |
RWT.PASSWORD | RWT.BORDER);
Button loginButton = new Button( content, RWT.PUSH );
loginButton.setText( "Login" );
loginButton.addSelectionListener( new SelectionAdapter() {
public void widgetSelected( final SelectionEvent event ) {
Traza.test("CLOSING...");
((Button)event.getSource()).getShell().close();
}
});
content.layout();
}
}

Hi Roberto,
that really looks sad. One of the reasons is a current shortcoming of
the RowLayout. For now You have to set RowData(width,heigh) for each
control in a RowLayout. I would recommend to use a (1 column) GridLayout.
The controls demo shows a login dialog that is quite close to what You
want to achieve. Maybe have a look at DialogsTab in the
org.eclipse.rap.demo plug-in.

Thank you Rüdiger, Using ".setLayoutData" for every control the problem
was solved, But only using GridLayout It was the same, at least I had to
use GridLayout with GridData. The final code is really "ugly", It's a
bit difficult to design good interfaces with a lot of controls. I think
that It's very interesting (almost necessary) compatibility with Visual
Editor, It's my oppinion.
Now I don't extend from Shell I've implemented a mini-wrapper over the
Shell object.

Hi Roberto,
You don't need to switch to GridLayout and layout explicitly by
providing all the layout data, just provide layout data for the rows:
e.g. image.setLayoutData( new RowData( 100, 70 ) );
and datos.setLayoutData( new RowData( 200, 100 ) );
That should cure the problem.
Jochen
P.S: It is also important to know that we can not determine the size of
images right now. You should provide info on bounds for all images for
layouts to work.

Hi Jochen, I know it, but in fact I'm using a "LayoutData" for every
element because in RowLayout I have 1 element for every row.
Besides, in this situation, I prefer GridLayout, witch with only 1
column is as simple as RowLayout and for every element I have more
options (GridData is more customizable than RowData) I'm using "new
GridData(width, height);" and "new GridData(GridData.BEGINNING,
GridData.BEGINNING, true, true);" depending on the control
I would prefer RowData if I hadn't to set elements height, but if I have
to do it, GridLayout/GridData give me more "possibilities"
In any case, Thanks for your advice.
Regards.
Roberto.
