QAbstractEventDispatcher: INTERNAL ERROR, timer ID 0 is too large

[jasonhxs]

Hi,

I used QTreeView and QStandardItemModel to model the scope tree.
Now the parent node has lots of children and sub-children nodes (probably million nodes).
I suffer a crash when updateGeometries() for the tree view.

The message is:

Fatal: QAbstractEventDispatcher: INTERNAL ERROR, timer ID 0 is too large
catch signal 6

The call-stack is:

Do you have any idea about this, thanks.

When exactly does the crash occur? The trace seems to indicate you were inserting some rows into the model. How many rows?

We got a solution, insert the children by group, so the calling of "QAbstractItemModel::rowsInserted" will be reduced, and time ID is not overflow.
