Scrolling QTableWidget smoothly

由 孤街浪徒 提交于 2019-12-08 08:52:24
问题 I have a QTableWidget with custom Widgets. These widgets are big and fill almost the whole scroll area in height, so that only one row is visible. I can scroll with the mouse wheel or by dragging the scroll bar, but the row always jumps. Is there a way to configure the QTableWidget to smoothly scroll, without jumping? 回答1: Try to use this: view->setVerticalScrollMode(QAbstractItemView::ScrollPerPixel) From Qt documentation: enum ScrollMode { ScrollPerItem, ScrollPerPixel } verticalScrollMode

How to limit the selection in a QTableWidget

由 橙三吉。 提交于 2019-12-07 05:23:25
问题 How would I go about limiting the rows/columns selected in a QTableWidget? I need to force the user to use a contiguous selection (already done) to select exactly two columns and any amount of rows. Thanks! 回答1: You will probably have to do one of 2 things: You would have to subclass QItemSelectionModel and implement functions for adding and deleting selected QModelIndex es so that you only add items from 2 rows to it. You can do this by having a custom implementation for catching signals
