ComboBox filtering treeWidget ?

Heya

Hello,
I got a combobox called " filters " with 2 items in it(blue and red)
And a treewidget called tree1 with 2 columns ( name and color )
What i want is that if i choose "red" as filter in my combobox, only item with "red" as color would be showed on my treewidget.

i've heard i should use QSortFilterProxyModel but i have no idea how to do

Thanks

(python)

Hi,

Please have some patience and allow 24 hours before bumping your own thread. This is a community forum with people not necessarily living in the same time zone as you.

As for your question, you're likely looking to use QSortFilterProxyModel:: filterRegExp with the content of your combo box.

separate QTreeWidget in a QTreeView and a QStandardItemModel.
create a QSortFilterProxyModel and set the QStandardItemModel as its suorce model
connect currentTextChanged from the combobox to setFilterFixedString of QSortFilterProxyModel
if you need the filtering to be recursive then you can replace QSortFilterProxyModel with KRecursiveFilterProxyModel (I have no idea if/how you can use it in python though)

Heya

Sorry but could you just give me the code ?

I tried:

tree1 = QTreeWidget()
sourceModel = MyItemModel()

proxyModel = QSortFilterProxyModel()
tree1.setModel(proxyModel)
proxyModel.setFilterRegExp(QRegExp(".PNG", Qt.CaseIntensive,QRegExp.FixedString))

ui.filters.CurrentIndexChanged.connect(?)

I used PySide doc as example

IIRC something like:

ui.filters.currentTextChanged.connect(proxyModel.setFilterFixedString)
