separate QTableWidget into a QTableView and a QStandardItemModel
add a QSortFilterProxyModel as the model of QTableView and set the QStandardItemModel as the QSortFilterProxyModel's sourceModel
call QSortFilterProxyModel::setFilterWildcard or QSortFilterProxyModel::setFilterRegExp to perform the searching
Actually I did try setting QTabWidget setAutoFillBackground(True) previously, but it didn't work.
Now I tried set VGroupBox setAutoFillBackground(True), then the color changed to light grey which is the exact default color I need.
You'll need to change the context to the second GL widgets before using it.
As each time you render or do anything with OpenGL setup/parameters that you have the right context selected first for each widget.
@Masonsu your QTextEdit is an implementation detail of your Chatlog widget. You should use e.g. a slot in Chatlog that will internally append the text to your QTextEdit. So if you change it for something else. You don't have to rewrite everything because of that.
That's definitely a bug. There seems to be a bug report about it QTBUG-15203, but it has been closed due to Qt4 EOL. Since it's still valid please report it for Qt5.
As for a workaround I'm afraid you will need to paint the tabs yourself. If you don't wan't to subclass and override paintEvent you can install an event filter and handle the painting there. Other that that I can't think of any other solution, apart maybe from adding some spaces to the front of the strings :P (just kidding, don't do it).
El problema era que cuando hace el primer remove los indices cambian, así que cuando elimino el indice 1 los indices pasan de ser 0,1,2 a ser 0,1. El segundo remove intenta eliminar el indice 2 pero este dejó de existir cuando hace el primer remove.
Así que la solución es esta:
Thanks mrjj and Chris Kawa for your valuable response.
Actually I want to create my own customized scroll-button for tabBar with either end button( two buttons like << and >> including qt already provided scroll-buttons < and >) So that we can directly go to the fist or last tab. In Qt scroll-button for Qtabbar provides only step forward or backward functionality means we can scroll only one tab at a time.
Suppose my QTabBar contains 100 tab and currently visible tabs are 55,56,and 57 and if we want to go on first then we have to click approx 49 times or stay in clicked state for few seconds.
if you guys have any approach for doing this efficiently then please. It would be highly appreciated.
