Getting errormarkers of xtext editor [message #1792945]

Hi anybode,

I want to implement a test, which checks if there are bullets available in the editor. I have done it this way:
SWTBotEclipseEditor textEditor = swtBot.activeEditor().toTextEditor();
for (int currentLine = 0; currentLine < textEditor.getLineCount(); currentLine++) {

if (textEditor.hasBulletOnLine(currentLine))
errorMarkers.add("Line " + currentLine + ":" + textEditor.getBulletOnLine(currentLine).text);
}

But although I see error markers in different lines in real, swtbot does not detect them. So my question:
- Are the bullets really the error markers you see in the editor?
- Did I implement something incorrectly or do I have another option to get to this information?

Thanks in advance
Cheers
Markus

Hi Markus,

For SWTBot to find the bullets with the code above, the active editor must be implemented with a workbench part that contains a StyledText widget, and this widget must be decorated (by the application) using the API StyledText.setLineBullet().

I'm not too familiar with the implementation, but it seems to me that an AbstractDecoratedTextEditor is created with a VerticalRuler on the left and an OverviewRuler on the right. Both of those use a Canvas widget and probably do their own drawing, not using the line bullet API.

Hi Patrick,

looks so.. but the Rulers are protected :-(
