org.eclipse.swt.widgets.Text character limit

Question

I am using org.eclipse.swt.widgets.Text I am doing

Text description = new Text(container, SWT.SINGLE);
description.setEditable(false);
description.setText("long string");

About half of the text shows up in the wizard that I am creating. I see there is a static int called LIMIT in the API. I have not been able to find where it states there is a preset on the number of characters that the Text can hold. I want to expand this to the number of characters that I need.

`LIMIT` is 0x7FFFFFFF except on very old versions of Windows when it is 0x7FFF. — greg-449, Sep 17 '14 at 13:47
So I am using the setText method. The text is ~100 characters long. So the text is NOT being cutoff because of the Text object? — Chris Bolton, Sep 17 '14 at 14:05
I just got 200 characters in a Text control (Mac OS X). Note that the control will not resize to show long text. — greg-449, Sep 17 '14 at 14:15
So the Text box is not large enough to display all of the text. When I make it editable and enabled, I am see that the text is showing up. I just need to make the text box larger. — Chris Bolton, Sep 19 '14 at 13:37

As the API mentiones, Text.LIMIT is a hard limit of the underlying native widget implementation. You can set the limit to another value using Text.setTextLimit(), but not larger than Text.LIMIT.

Maybe your text is not showing up, because you are using the single-line version of Text. Try instead

Text description = new Text(container, SWT.MULTI);

If it's also not working, try another widget without this limitation (e.g. StyledText).

I would say that would not work indeed when using the multi-line text with the `SWT.MULTI` style bit. Looking at the source code, the limit is only applied when the `SWT.SINGLE` bit is set (org.eclipse.swt.gtk.linux.x86_64_3.105.3.v20170228-0512.jar). – Campa Jan 24 '20 at 10:58

Text.LIMIT (2,147,483,647 or 2^31) is the maximum number of characters that can be entered into a text widget. This value can change for each version of eclipse.
