Ticket #4041 - Lost navigation cube labels

[openBrain]

.... I wonder if this is also related to the QT version and Intel GPU/Driver?

Not that time I think. No problem here with an Intel GPU.

Same issue in german forum, like chrisb mentioned,
walks along with this error message in report view:

Code: Select all

XmbTextListToTextProperty result code -2

Same in your case?

On my system labels are visible but letters are squashed together.

Anyone find a solution to this?

Does that change something if you change the app font?

Code: Select all

from PySide import QtGui
Gui.getMainWindow().setFont(QtGui.QFont("Mono", 10, QtGui.QFont.Normal, False))

Thank you. Sadly, it did not help the labels in the Navigation Cube.
Any idea where the Navigation Cube takes its font from?
The Xmb error (XmbTextListToTextProperty result code -2) appears throughout the log file, but I have no idea of its significance.

So i went looking around for a solution. I looked in the source code and saw the navigation cube used "Helvetica" font. I searched my system and I did not have Helvetica. It is proprietary but I found a free sample and downloaded it and installed the font on my system and now the labels can be seen.

This problem could be resolved by using a different font in the navigation cube.

'Hold your horses there fella' not sure this is Solved just yet. You found a workaround but not a solution. A solution would entail having a conditional check to see if said font in the system before setting it as the font for FC. Oh and another thing, are u saying that Helvetica (a proprietary font) is a hardcoded default in to FC??

[leong]

Thank you for the correction. You are correct, it is "solved" for me. My workaround was based on finding the following in NaviCube.cpp for 0.19

Code: Select all

if (text) {
		paint.setPen(Qt::white);
		QFont sansFont(str("Helvetica"), 0.18 * texSize);
		sansFont.setStretch(QFont::ExtraCondensed);
		paint.setFont(sansFont);
		paint.drawText(QRect(0, 0, texSize, texSize), Qt::AlignCenter,qApp->translate("Gui::NaviCube",text));
	}

and on the fact that changing the font in preferences had not effect on the navigation cube.
As I do not do coding (and my little knowledge is likely a dangerous thing), I leave it to you to say whether or not that constitutes harcoding the font into FC.

I doubt that is the problem since the text shows perfectly here for me and as far as I can tell I don't have Helvetica on this system, at least not that I can find. Wouldn't the system substitute the font with another if it can't find Helvetica?
