Inheritance diagram for KexiDBComboBox:

Detailed Description
Combo box widget for Kexi forms.This widget is implemented on top of KexiDBAutoField, so as it uses KexiDBAutoField's ability of embedding subwidgets, it can display not only a line edit but also text edit or image box (more can be added in the future). A drop-down button is added to mimic native combo box widget's functionality.

virtual KexiTableViewColumn* KexiDBComboBox::column | ( | ) | const [inline, virtual] |
Implemented for KexiComboBoxBase: form has no 'related data' model (only the full database model).
Implements KexiComboBoxBase.
Definition at line 50 of file kexidbcombobox.h.
virtual KexiDB::Field* KexiDBComboBox::field | ( | ) | const [inline, virtual] |
Implemented for KexiComboBoxBase.
Implements KexiComboBoxBase.
Definition at line 53 of file kexidbcombobox.h.
virtual QVariant KexiDBComboBox::origValue | ( | ) | const [inline, virtual] |
Implemented for KexiComboBoxBase.
Implements KexiComboBoxBase.
Definition at line 56 of file kexidbcombobox.h.
virtual QVariant KexiDBComboBox::value | ( | ) | [inline, virtual] |
- Returns:
- value currently represented by this item.
Reimplemented from KexiDBAutoField.
Definition at line 63 of file kexidbcombobox.h.
bool KexiDBComboBox::valueChanged | ( | ) | [virtual] |
Reimpemented because to avoid taking value from the internal editor (index is taken from the popup instead).
Reimplemented from KexiDBAutoField.
Definition at line 396 of file kexidbcombobox.cpp.
void KexiDBComboBox::setColumnInfo | ( | KexiDB::QueryColumnInfo * | cinfo | ) | [virtual] |
Reimplemented after KexiDBAutoField: jsut sets cinfo without initializing a subwidget.
Initialization is performed by setVisibleColumnInfo().
Reimplemented from KexiDBAutoField.
Definition at line 403 of file kexidbcombobox.cpp.
void KexiDBComboBox::setVisibleColumnInfo | ( | KexiDB::QueryColumnInfo * | cinfo | ) | [virtual] |
Used internally to set visible database column information. Reimplemented: performs initialization of the subwidget.
Reimplemented from KexiFormDataItemInterface.
Definition at line 408 of file kexidbcombobox.cpp.
KexiDB::QueryColumnInfo * KexiDBComboBox::visibleColumnInfo | ( | ) | const [virtual] |
- Returns:
- visible database column information for this item. Reimplemented.
Reimplemented from KexiFormDataItemInterface.
Definition at line 415 of file kexidbcombobox.cpp.
const QColor& KexiDBComboBox::paletteBackgroundColor | ( | ) | const [inline] |
Reimplemented to return internal editor's color.
Reimplemented from KexiDBAutoField.
Definition at line 84 of file kexidbcombobox.h.
void KexiDBComboBox::setPaletteBackgroundColor | ( | const QColor & | color | ) | [virtual] |
Reimplemented to also set 'this' widget's background color, not only subwidget's.
Reimplemented from KexiDBAutoField.
Definition at line 384 of file kexidbcombobox.cpp.
void KexiDBComboBox::undoChanges | ( | ) | [virtual] |
Undoes changes made to this item - just resets the widget to original value. Reimplemented after KexiFormDataItemInterface to also revert the visible value (i.e. text) to the original state.
Reimplemented from KexiComboBoxBase.
Definition at line 531 of file kexidbcombobox.cpp.
void KexiDBComboBox::slotRowAccepted | ( | KexiTableItem * | item, | |
int | row | |||
) | [virtual, slot] |
Call this from slot.
Reimplemented from KexiComboBoxBase.
Definition at line 514 of file kexidbcombobox.cpp.
void KexiDBComboBox::slotItemSelected | ( | KexiTableItem * | item | ) | [inline, virtual, slot] |
Call this from slot.
Reimplemented from KexiComboBoxBase.
Definition at line 96 of file kexidbcombobox.h.

QRect KexiDBComboBox::editorGeometry | ( | ) | const [protected] |
void KexiDBComboBox::createEditor | ( | ) | [protected, virtual] |
Creates editor.
Reimplemented, because if the combo box is not editable, editor should not be created.
- Todo:
- Qt4: set transparent background, for now we're setting button color
