Has great god guiding qtable qtreeview biggest shows how much is the amount of data, can display without affecting the scrolling, seemingly qtreeview parent node, and have obvious lay there are more than 3000 nodes below, appear, scroll up and down the rolling caton, in Java, data load 100000 data won't appear obvious caton, I think, qt control performance of not less than the swing, middle and a virtual machine, after all, which the great spirit show???

The stand or fall of this thing and you write the model of relationship is very big

CodePudding user response:

You compare the qtreeview and series, not a thing, I'm here for performance, limit qtable display up to 10000 data, otherwise will be paged, display speed quickly, but qtreeview display speed is very slow, I also have a headache, and my solution is opportunistic, children is not opened more than 100, anyway, I this is three states the tree, not expand user also know what is going on, but the plan is only applicable to my software, but we can discuss, in what way to fundamentally solve this problem, at least as performance hopes to achieve qtableview qtreeview article (article 10000 data quickly, 100000 is caton),

Focus on this problem!!!!!!
