[Qt-interest] Qt Symbian: Panic BITGDI 13 in QWebview

[Mattia Roberto]

Hi all,

I am developing an application based on QT 4.6.0 for Symbian S60.
This application loads a local html file and displays it using QWebView.
The purpose of this html file is to display an interactive map with additional routes information
The html file includes external JavaScript library served by a remote map server.

One of the API provided by the remote JavaScript library is used to draw some colored lines by using HTML5's new tag <canvas>.


The application can work well using N97 mobile phone.
However when trying it with S60 5th edition SDK emulator, or N97 SDK emulator,
when the application starts to invoke this API to draw <canvas> related lines, emulator crashes with panic BITGDI 13(error about invalid bitmap):

BitGdi internal Panic EBitgdiPanicInvalidBitmap, in file BITMAPDV.CPP @ line 47
Assert condition = "aFbsBitmap != NULL"


If trying the same application in N97 Mini Mobile Phone or Nokia 5800 Xpress Music, at the same point, application panic and exits immediately.

I was wondering if anyone already experimented use of canvas tag in webkit and had similar panic notification.

Thanks for your help in advance.

Roberto Mattia
