Hi folks,
i have issues in showing huge data in QTableView ,data read from
sqlite database which is being updated dynamically .. 2k rows in 2s.
i am using QSQLRelationModel
let me describe the scenario in detail.
My Qt application has a view i.e QTableView , each row has following
structure:
****************************************
*QPushButton*|QLabel | QLabel | QLabel *
****************************************
i have created it using QItemDelegate
each row isinserted dynamicaly , after sometime gui gets freezed.
could anyone tell me the way to fix the issue.
Don't implement it like this. You are creating 8k widgets and act
suprised that it isn't fast... Even if you did not use QLabel but the
default delegate, 2k push buttons is still pushing it I think.
Note that this is by no means a new issue. Search and you will find
better options, even ones using widgets but creating far less instances.
André
