qtableview

问题 How to add spaces between table cells using QSS selectors. I've tried the border-spacing selector, the item pseudo-class with the border selector, but it all doesn't work as it should.

问题 I'm writing a unit test for a custom Validator in a QTableView using the QTestLib framework. One of the most basic test cases could be described like this: Double click the table cell in the third column and the fourth row, and append the number '5' to its content. It is not sufficient to simply change the value in the model or anything, the test case shall perform it like this: Double Click the table cell to set it into edit mode Press the [End] key. Press the [5] key. Note: This question

问题 I am working on a test case editor. This editor contains USART a transmit and receive packet format. The editor is a table view. The transmit and receive packet is eight bytes long, for example: 0x01 0x02 0x03 ... 0x08 It is in my fifth and sixth column. Now, I want the cells in this column to be read only, but when I double-click on any cell in these columns a pop-up widget is displayed. This widget will contain eight boxes in the text edit, where the user can enter the packet format (i.e.
