RAP appears to calculate the width/height of a Label incorrectly on Chrome (37) for certain fonts.
I used "Bauhaus 93" font, and for an instance the Label displays the full text, then after a momentary delay, it shrinks the size of the Label hiding the last word of text in the Label as a consequence.
Here is a snippet:
/* DEMONSTRATES RAP issue with unusual font sizes/styles - label not big enough */
package bug.snippet;
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.graphics.Font;
import org.eclipse.swt.graphics.FontData;
import org.eclipse.swt.graphics.RGB;
import org.eclipse.swt.layout.FormAttachment;
import org.eclipse.swt.layout.FormData;
import org.eclipse.swt.layout.FormLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
public class Bugsy {
private Display display;
private Shell shell;
private static Label lab;
public void begin() {
System.out.println("BugSnippy Starting...");
// create the Shell
display = new Display();
shell = new Shell(display, SWT.TITLE|SWT.CLOSE|SWT.RESIZE);
shell.setText("Shell");
shell.setFullScreen(true);
shell.setBackground(new Color(null, new RGB(255,192,255)));
FormLayout layout = new FormLayout();
shell.setLayout(layout);
//create the label
lab = new Label(shell, SWT.NONE);
lab.setText("Wonderful stuff is great and fab");
FontData fontData;
fontData = new FontData();
fontData.setName("Bauhaus 93");
fontData.setStyle(SWT.NONE);
fontData.setHeight(20);
Font font = new Font(display, fontData);
lab.setFont(font);
//set label's position
FormData fd = new FormData();
fd.left = new FormAttachment(0, 5);
fd.top = new FormAttachment(0, 50);
lab.setLayoutData(fd);
shell.open();
System.out.println("BugSnippy Done!");
}
}
A screen shot to help explain...
Thanks, John

Hi.
If it's reproduceable in RAP 2.3 or later, just open a bugzilla entry
with that snippet and possibly instructions how to get that font.
Greetings,
Tim
