I have a custom widget for displaying thumbnail images. The widget stops displaying when there is a large number of images.

1. The widget is a subclass of QScrollArea
2. A QFrame widget is instantiated and is set as the main scroll widget
3. A QGridLayout widget is instantiated and is the main layout widget
4. For each thumbnail image, a QLabel is created and added to the grid layout. Currently there is only one row with 0..n columns. THe rowSpan and columnSpan size is 3
5. I am adding the label widgets with this call
gridLayout->addWidget( label, row, column, 3, 3);

The images are displayed correctly until the number of images exceeds 40. When attempting to display more images, none of the images are displayed. Is there a scroll area size that needs to be set?

Thanks
