new Text(parent, SWT.MULTI | SWT.V_SCROLL); used to create a text area with vertical scrolling in RAP 1.4

1.5 nightly doesn't scroll.

Where did it go? It's a subclass of Scrollable so should support V_SCROLL and H_SCROLL

Hi Chris,
if it's working as expected in RAP 1.4 but not in latest nightly, it's
probably a regression. Could you open a bugzilla about this issue. What
do you mean by doesn't scroll? Vertical scrollbar is missing or it is
there but you couldn't drag it?
Best,
Ivan

Hi.

I just want to give some notes for a better technical overview.
The RAP Text widget does not "support" V_SCROLL and H_SCROLL insofar
that it is based on the html textarea element. (This was also true in
1.4.) This element always scrolls if the text doesn't fit, and shows no
scrollbars if it does fit. Its not possible to change that.

To properly support H_SCROLL and V_SCROLL, a completely new
implementation of Text would be needed. In 1.5 we did make changes to
Text, but its still based on textarea. Thats why i'm not sure how there
could be any differences between 1.4 and 1.5 regarding scrolling.

Greetings,
Tim

in 1.5 nightly, the Text widget still scrolls when text does not fit like it used to, but scroll bars nolonger appear.

public class EntryPoint3 implements IEntryPoint {
	@Override
	public int createUI() {
		new Display();

		final Shell shell = new Shell(SWT.SHELL_TRIM);
		shell.setSize(200, 200);
		
		Text text = new Text(shell, SWT.BORDER | SWT.V_SCROLL | SWT.MULTI | SWT.WRAP);
		text.setBounds(50, 50, 100, 105);
		
		shell.setVisible(true);
		
		return 0;
	}
}

This snippet should have a vertical scrollbar visible when there is too much text to show in the widget. It doesn't. You can still scroll up and down using the up and down keys though.

Works as expected in SWT on windows and RWT 1.4
