根据文本长度的tableviewcolumn的动态高度

Question

hello I have the following problem I am working with qt quick control 1.4 because the tableview of 2.15 does not adapt correctly as I would like; the table overflows in height and my question is the following can you make a dynamic height and that can be adding say 15 to the default height

example: the default height is 50

can you add 15 or 10 depending on the length of the text?

}

I have looked for different solutions and none of them fits the text, if you could help me I have been struggling with this for days I would appreciate it in advance.

Answer 1

I've added a property maxSize and modified it every time the contentHeight of one cell changes to something bigger than maxSize .
