Custom fonts only works the first time QML

votes

I am really struggling with this and not sure how to solve this issue.

Here is the code.

I am running this on symbian ^3 (belle)

I have 2 custom fonts that i need to use.

In the example below i have created 3 buttons.
1. Display gurbaniwebthick.ttf
2. Display GurHindi.ttf.
3. Quit.

This works on N9

I click on the first button and then click on text filed it displays the first line in Pubjabi.

Click on the second button and then click on the text filed it displays the first line in Hindi.

When i quit the app and then run the app again the fonts are not applied. Its like it can’t get a lock on the file.

Please advise how to solve this issue.
