Hi,

i use a TreeField to display my items. In the treefieldcallback i do the painting stuff, but the treefield is acting really strange.

Heres the TreeFieldCallback Code:

public void drawTreeItem(TreeField treeField, Graphics graphics, int node,
			int y, int width, int indent) {
		Task item = (Task) treeField.getCookie(node);
		int tmp = graphics.getColor();
		if (treeField.getCurrentNode() == node) {
			graphics.setColor(Color.BLUE);
			graphics.fillRect(0, y, Display.getWidth(), treeField.getRowHeight());
			if (item.getType() == 0) {
				if (treeField.getExpanded(node)) {
					graphics.drawBitmap(3, y + 3, 15, 15, minus_icon, 0, 0);
				} else {
					graphics.drawBitmap(3, y + 3, 15, 15, plus_icon, 0, 0);
				}
			}
		} else {
			switch (item.getType()) {
			case 1:
				graphics.setColor(Color.BEIGE);
				graphics.fillRect(0, y, Display.getWidth(), treeField.getRowHeight());
				break;
			case 0:
				graphics.setColor(Color.ROSYBROWN);
				graphics.fillRect(0, y, Display.getWidth(), treeField.getRowHeight());
				if (treeField.getExpanded(node)) {
					graphics.drawBitmap(3, y + 3, 15, 15, minus_icon, 0, 0);
				} else {
					graphics.drawBitmap(3, y + 3, 15, 15, plus_icon, 0, 0);
				}
				break;
			default:
				break;
			}
		}
		graphics.setColor(tmp);
		graphics.drawText(item.getTaskname(), indent, y);
	}

Which leeds to the following screen:

As you can see, in the top screenshot, the whole item is focused with a blue background. In the second screen, only a part of the row gets highligthed with the blue color. Which is strange, because the blue rect is painted at the same line of code.

Seems like i cant draw more left then the indent of the row. Is there a way to override this an color the full row?

Regards,

Grinarn

I have the same issue, does anyone know how to fix this?

EDIT:

I think it's due to the clipping rigions during the drawing, however i don't see a method anything in Graphics to expand the clipping region, only to reduce the size thereof.....any clues how to do that?

Would you please provide the Task class and its methods?
