Description
Description: When the size of a certain itme is different from others, Click key PageDown,The cursor position is displayed abnormally.Like the attached video.
Steps: Run the program and press Page Down on the keyboard. Observe the currently selected item
Reason: In the moveCursor function of QListview,
rect.moveTop(rect.top() + d->viewport->height()-2 * rect.height());
When the first item is relatively large, subtract 2* rect.height() Make the cursor position calculation abnormal.
Hope: Regardless of the size of the item, turning the page can jump to a page normally.
