Classes¶

ComboBoxDelegate¶

Simple ComboBox delegate with built-in tooltip support

Inherits from: QItemDelegate

Methods¶

init(self, values, parent)¶

Initializes a ComboBoxDelegate instance by calling the parent QItemDelegate constructor with the provided parent argument. Sets the values attribute to the supplied values list, defaulting to an empty list if None or a falsy value is provided. Sets the editable attribute to the string "False".

def_values(self, values)¶

Sets the values attribute of the delegate to the provided values parameter. This method replaces any previously assigned values with the new input.

def_editable(self, editable)¶

No description available. Sets the editable attribute of the instance to the provided value. This method assigns the given editable argument directly to self.editable, controlling whether the associated component permits editing.

Signature: def_editable(self, editable)

Parameter	Description
`editable`	The value assigned to `self.editable`.

createEditor(self, parent, option, index)¶

No description available. Creates and returns a QComboBox widget to be used as a cell editor. The combo box is populated with all items from self.values, configured with a maximum of 10 visible items, and its size is adjusted to fit its contents. A tooltip displaying the current selection is set and updated on each selection change; the editability of the combo box is determined by the editable attribute if present and non-empty, otherwise it defaults to non-editable.

setEditorData(self, editor, index)¶

No description available. Populates the delegate's editor widget with data retrieved from the model at the given index. It fetches the display text via Qt.DisplayRole, locates the corresponding entry in the editor using findText, and falls back to index 0 if no match is found. The editor's current selection is then set to the resolved index, and its tooltip is updated to display "Valore corrente: " followed by the currently selected text.

setModelData(self, editor, model, index)¶

No description available. Transfers data from the editor widget back to the model. Retrieves the current text from the editor and writes it to the model at the specified index using model.setData. This method follows the standard delegate interface for committing user-edited values to the underlying data model.
