  • PyQt4 and QTableView with spinbox and checkbox

    - by ekapek
    Hi, I have a QTableView with QSqlTableModel and with 3 columns, now I need to have: - second column: spinbox after clicked to edit - third column: checkbox (displayed center) My code: class SpinBoxDelegate(QtGui.QItemDelegate): def createEditor(self, parent, option, index): editor = QtGui.QSpinBox(parent) editor.setMinimum(0) editor.setMaximum(100) print 'spinbox' return editor def setEditorData(self, spinBox, index): value = index.model().data(index, QtCore.Qt.EditRole).toInt()[0] spinBox.setValue(value) def setModelData(self, spinBox, model, index): spinBox.interpretText() value = spinBox.value() model.setData(index, value, QtCore.Qt.EditRole) def updateEditorGeometry(self, editor, option, index): editor.setGeometry(option.rect) class myQSqlTableModel(QtSql.QSqlTableModel): def flags(self,index): result = QtSql.QSqlTableModel.flags(self,index); if index.column() == 2: result |= QtCore.Qt.ItemIsUserCheckable return result def data(self,index,role): if not index.isValid: return QtCore.QVariant() value = QtSql.QSqlTableModel.data(self, index, role) if index.column() == 2: if role == QtCore.Qt.CheckStateRole: return QtCore.Qt.Unchecked if QtSql.QSqlTableModel.data(self, index).toInt()[0] else QtCore.Qt.Checked elif role == QtCore.Qt.DisplayRole: return QtCore.QVariant() return value and self.model = myQSqlTableModel(self) self.model.setTable("person") self.model.setEditStrategy(QtSql.QSqlTableModel.OnManualSubmit) self.model.select(): self.model.setHeaderData(0, QtCore.Qt.Horizontal, self.tr("ID")) self.model.setHeaderData(1, QtCore.Qt.Horizontal, self.tr("A")) self.model.setHeaderData(2, QtCore.Qt.Horizontal, self.tr("B")) self.view = QtGui.QTableView() self.view.setModel(self.model) self.view.setSortingEnabled(True) spinDelegate = SpinBoxDelegate() self.view.setItemDelegateForColumn(1,spinDelegate) but it does't work: spinbox don't show after click and checkbox can't be clicked and is aligned to left Any help?

  • QListView/QListWidget with custom items

    - by Daniel
    I'm writing my first Qt application with PyQt and am having some trouble creating a custom list view. I'd like the list to contain arbitrary widgets (one custom widget in particular). How would I go about this? It seems that the alternative would be to create a table or grid view wrapped in a scrollbar. However, I'd like to be able to take advantage of the model/view approach as well as the nesting (tree-view) support the built-ins handle. EDIT: To clarify, this widget is interactive (contains buttons), so the solution requires more than painting a widget.

  • How does one paint the entire row's background in a QStyledItemDelegate ?

    - by Casey Link
    I have a QTableView which I am setting a custom QStyledItemDelegate on. In addition to the custom item painting, I want to style the row's background color for the selection/hovered states. The look I am going for is something like this KGet screenshot: Here is my code: void MyDelegate::paint( QPainter* painter, const QStyleOptionViewItem& opt, const QModelIndex& index ) const { QBrush backBrush; QColor foreColor; bool hover = false; if ( opt.state & QStyle::State_MouseOver ) { backBrush = opt.palette.color( QPalette::Highlight ).light( 115 ); foreColor = opt.palette.color( QPalette::HighlightedText ); hover = true; } QStyleOptionViewItemV4 option(opt); initStyleOption(&option, index); painter->save(); const QStyle *style = option.widget ? option.widget->style() : QApplication::style(); const QWidget* widget = option.widget; if( hover ) { option.backgroundBrush = backBrush; } painter->save(); style->drawPrimitive(QStyle::PE_PanelItemViewItem, &option, painter, widget); painter->restore(); switch( index.column() ) { case 0: // we want default behavior style->drawControl(QStyle::CE_ItemViewItem, &option, painter, widget); break; case 1: // some custom drawText break; case 2: // draw a QStyleOptionProgressBar break; } painter->restore(); } The result is that each individual cell receives the mousedover background only when the mouse is over it, and not the entire row. It is hard to describe so here is a screenshot: In that picture the mouse was over the left most cell, hence the highlighted background.. but I want the background to be drawn over the entire row. How can I achieve this? Edit: With some more thought I've realized that the QStyle::State_MouseOver state is only being passed for actual cell which the mouse is over, and when the paint method is called for the other cells in the row QStyle::State_MouseOver is not set. So the question becomes is there a QStyle::State_MouseOver_Row state (answer: no), so how do I go about achieving that?

  • How to make QCombobox painting item delegate for it's current Item? (Qt 4)

    - by r4nj33t
    QCombobox set Item delegate not painting for current Item.. I am trying to create a combo box showing different line types (Solid, Dotted, Dash etc). Currently i am setting item delegate for its content so as to draw/paint line type instead of displaying names. All line types are drawing currectly but as soon as i am selecting any line type from the combobox, the current index of combo box is displaying just the line name and not painting it. How can i make it paint the selected line type on the current combo box index?

  • 'C++ object destroyed' in QComboBox descendant editor in delegate

    - by Max
    Hi, all! I have modified combobox to hold colors, using QtColorCombo (http://qt.nokia.com/products/appdev/add-on-products/catalog/4/Widgets/qtcolorcombobox) as howto for the 'more...' button implementation details. It works fine in C++ and in PyQt on linux, but I get 'underlying C++ object was destroyed' when use this control in PyQt on Windows. It seels like the error happens when: ... # in constructor: self.activated.connect(self._emitActivatedColor) ... def _emitActivatedColor(self, index): if self._colorDialogEnabled and index == self.colorCount(): print '!!!!!!!!! QtGui.QColorDialog.getColor()' c = QtGui.QColorDialog.getColor() # <----- :( delegate fires 'closeEditor' print '!!!!!!!!! ' + c.name() if c.isValid(): self._numUserColors += 1 #at the next line currentColor() tries to access C++ layer and fails self.addColor(c, self.currentColor().name()) self.setCurrentIndex(index) ... Maybe console output will help. I've overridden event() in editor and got: ... MouseButtonRelease FocusOut Leave Paint Enter Leave FocusIn !!!!!!!!! QtGui.QColorDialog.getColor() WindowBlocked Paint WindowDeactivate !!!!!!!!! 'CloseEditor' fires! Hide HideToParent FocusOut DeferredDelete !!!!!!!!! #6e6eff ... Can someone explain, why there is such a different behaviour in the different environments, and maybe give a workaround to fix this. Here is minimal example: http://docs.google.com/Doc?docid=0Aa0otNVdbWrrZDdxYnF3NV80Y20yam1nZHM&hl=en
