[PyQt] QListView SelectAll Checkbox
Hi, I have a QListView, I also have a separate checkbox to do selectAll, deselectAll functionality, and It's working. but I am missing one thing, when I do selectAll, then deselect one item, The SelectAll checkbox should be cleared. I have been trying to figure out a way to do that but can't find the right way to do It. Here is what I have done so far: I have conntected the listView.selectionModel() 'selectionChanged' signal to toggle_groups_checkbox, In there I try to print the count of deselected items, and if it's more than 0 I clear the checkbox, but printing the count of deselected_items is not accurate, when I do selectAll it prints many values, one of them deselectedItems is 1... that would make me clear the checkbox, which is wrong. I think there is a better way to do that, so any guidance would be appreciated. self.connect(self.ui.listView_gateway_groups.selectionModel (), SIGNAL(selectionChanged(const QItemSelection,const QItemSelection)), self.toggle_groups_checkbox) def toggle_groups_checkbox(self, set_selection, clear_selection): print set_selection.count() print clear_selection.count() ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] QListView and QItemDelegate editor widget question
I'm trying to make a list where selecting an item opens an editing
widget of arbitrary size. Here's a simple example.
List with nothing selected...
___
Item 1
___
Item 2
___
Item 3
___
Item n
___
List with an item selected...
___
Item 1
___
Item 2
Label: |___|
Label: |___|
_
| Calendar
| or other widget
|_
___
Item 3
___
Item n
___
I modified the spinbox example and got this...
___
Item 1
___
Big spinbox here
___
Item n
___
The spinbox widget simply covers up entries 3 through n.
I'm assuming that it has something to do with the sizeHint and paint
methods of the ItemDelegate. But I'm not sure. Is this even possible
with a listview or am I wasting my time?
The shortest version I could make of my code is below. Basically it
is a copy of the spinbox example with the QStandardItemModel replaced
with a QAbstractListModel and the QTableView replaced with a
QListView. Sorry if there's some ugly bits in there I've been trying
to figure this out for days and I'm pretty much just fumbling around
in the dark by now.

[PyQt] QListView Global funcation behaviour
hey folks; I am trying to list photos on QlistView by browsing using Qfiledailoug... so far i was doing the following filename = QtGui.QFileDialog.getOpenFileName(self, 'Open file','/home/') #this one calls the file dailoug for browsing filename = [] # this one is an array to hold selected files filename = listViewitem1() # this one is suppose to list the files on listview anyway i was getting an error saying that there is no global name for (listViewitem1), so i had to define a global function for it. here it's filename = QtGui.QFileDialog.getOpenFileName(self, 'Open file','/home/') filename = [] filename = listViewitem1(filename, self) class listViewitem1(QAbstractListModel): def __init__(self, datain, parent=None, *args): datain: a list where each item is a row QAbstractTableModel.__init__(self, parent, *args) self.filename = datain def rowCount(self, parent=QModelIndex()): return len(self.filename) def data(self, index, role): if index.isValid() and role == Qt.DisplayRole: return QVariant(self.filename[index.row()]) else: return QVariant() Then it runs with no errors but when i browse through my directory and select a file, nothing happens (no file is listed on QListView) and no errors occurred either. Any ideas will be so helpful Thank you -- View this message in context: http://www.nabble.com/QListView-Global-funcation-behaviour-tp22269640p22269640.html Sent from the PyQt mailing list archive at Nabble.com. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] qlistview
hi, I'm quite newbie in pyqt, so maybe my question is silly but I couldn't find answer with google helps. I want to know when the user clicks on my listview. Now I'm using void clicked (const QModelIndex) signal but it isn't what I want, signal is emitted only when then index is valid. It is also interesting for me when index is invalid. How can I do this? Thanks in advance for help. Regards Krzychu ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
