Hey all,

Would anyone be able to post a small example showing how to align a gtk.Label to the left when adding it to a gtk.Table? I am not sure how to do this, but the default seems to center the label text. Any help would be greatly appreciated.

Thanks in advance,
Zane

You can use gtk.Alignment to align widgets.

Code:
myTable.attachDefaults(Alignment.east(new Label("My Label")), 0, 1, 2, 3);

Thanks for the quick reply. Your example seems easy enough, but when I try to add three labels like this:

Code:
table.attach(Alignment.west(new Label("Hello World")),0,1,0,1,GtkAttachOptions.SHRINK, GtkAttachOptions.SHRINK, 4, 4);

   table.attach(Alignment.west(new Label("123")),1,2,0,1,GtkAttachOptions.SHRINK, GtkAttachOptions.SHRINK, 4, 4);

   table.attach(Alignment.west(new Label("test")),0,1,1,2,GtkAttachOptions.SHRINK, GtkAttachOptions.SHRINK, 4, 4);


They don't appear to align correctly. Instead the labels still appear to be centered like:

Code:
Hello World      123

    test


Instead I expected:

Code:
Hello World      123

test


Am I doing something wrong?

Thanks much,
Zane

use GtkAttachOptions.FILL, when using SHRINK the Alignment widget only uses the space it needs to display the Label. and the alignment widget is centered in the cell. By using FILL the Alignment widget fills the cell and aligns the Label to the left within it's self.

Code:
table.attach(Alignment.west(new Label("Hello World")),0,1,0,1,GtkAttachOptions.SHRINK, GtkAttachOptions.SHRINK, 4, 4);
table.attach(Alignment.west(new Label("123")),        1,2,0,1,GtkAttachOptions.SHRINK, GtkAttachOptions.SHRINK, 4, 4);
table.attach(Alignment.west(new Label("test")),       0,1,1,2,GtkAttachOptions.FILL, GtkAttachOptions.SHRINK, 4, 4);
