Detailed Description

Base class for custom wxPropertyGrid editors.

Remarks
  • Names of built-in property editors are: TextCtrl, Choice, ComboBox, CheckBox, TextCtrlAndButton, and ChoiceAndButton. Additional editors include SpinCtrl and DatePickerCtrl, but using them requires calling wxPropertyGrid::RegisterAdditionalEditors() prior use.
  • Pointer to built-in editor is available as wxPGEditor_EditorName (eg. wxPGEditor_TextCtrl).
  • Before you start using new editor you just created, you need to register it using static function wxPropertyGrid::RegisterEditorClass(), with code like this:
    wxPGEditor* editorPointer = wxPropertyGrid::RegisterEditorClass(new MyEditorClass(), "MyEditor");
    After that, wxPropertyGrid will take ownership of the given object, but you should still store editorPointer somewhere, so you can pass it to wxPGProperty::SetEditor(), or return it from wxPGEditor::DoGetEditorClass().

Constructor & Destructor Documentation

wxPGEditor::wxPGEditor ( )

Constructor.

virtual wxPGEditor::~wxPGEditor ( )
virtual

Destructor.

Member Function Documentation

virtual bool wxPGEditor::CanContainCustomImage ( ) const
virtual

Returns true if control itself can contain the custom image.

Default implementation returns false.

virtual wxPGWindowList wxPGEditor::CreateControls ( wxPropertyGrid propgrid,
wxPGProperty property,
const wxPoint pos,
const wxSize size 
) const
pure virtual

Instantiates editor controls.

Parameters
propgridwxPropertyGrid to which the property belongs (use as parent for control).
propertyProperty for which this method is called.
posPosition, inside wxPropertyGrid, to create control(s) to.
sizeInitial size for control(s).
Remarks
virtual void wxPGEditor::DeleteItem ( wxWindow ctrl,
int  index 
) const
virtual

Deletes item from existing control.

Default implementation does nothing.

virtual void wxPGEditor::DrawValue ( wxDC dc,
const wxRect rect,
wxPGProperty property,
const wxString text 
) const
virtual

Draws value for given property.

virtual wxString wxPGEditor::GetName ( ) const
virtual

Returns pointer to the name of the editor.

For example, wxPGEditor_TextCtrl has name "TextCtrl". If you dont' need to access your custom editor by string name, then you do not need to implement this function.

virtual bool wxPGEditor::GetValueFromControl ( wxVariant variant,
wxPGProperty property,
wxWindow ctrl 
) const
virtual

Returns value from control, via parameter 'variant'.

Usually ends up calling property's StringToValue() or IntToValue(). Returns true if value was different.

virtual int wxPGEditor::InsertItem ( wxWindow ctrl,
const wxString label,
int  index 
) const
virtual

Inserts item to existing control.

Index -1 means end of list. Default implementation does nothing. Returns index of item added.

virtual bool wxPGEditor::OnEvent ( wxPropertyGrid propgrid,
wxPGProperty property,
wxWindow wnd_primary,
wxEvent event 
) const
pure virtual

Handles events.

Returns true if value in control was modified (see wxPGProperty::OnEvent() for more information).

Remarks
wxPropertyGrid will automatically unfocus the editor when wxEVT_TEXT_ENTER is received and when it results in property value being modified. This happens regardless of editor type (ie. behaviour is same for any wxTextCtrl and wxComboBox based editor).
virtual void wxPGEditor::OnFocus ( wxPGProperty property,
wxWindow wnd 
) const
virtual

Extra processing when control gains focus.

For example, wxTextCtrl based controls should select all text.

virtual void wxPGEditor::SetControlAppearance ( wxPropertyGrid pg,
wxPGProperty property,
wxWindow ctrl,
const wxPGCell appearance,
const wxPGCell oldAppearance,
bool  unspecified 
) const
virtual

Called by property grid to set new appearance for the control.

Default implementation sets foreground colour, background colour, font, plus text for wxTextCtrl and wxComboCtrl.

The parameter appearance represents the new appearance to be applied.

The parameter oldAppearance is the previously applied appearance. Used to detect which control attributes need to be changed (e.g. so we only change background colour if really needed).

Finally, the parameter unspecified if true tells this function that the new appearance represents an unspecified property value.

virtual void wxPGEditor::SetControlIntValue ( wxPGProperty property,
wxWindow ctrl,
int  value 
) const
virtual

Sets control's value specifically from int (applies to choice etc.).

virtual void wxPGEditor::SetControlStringValue ( wxPGProperty property,
wxWindow ctrl,
const wxString txt 
) const
virtual

Sets control's value specifically from string.

virtual void wxPGEditor::SetValueToUnspecified ( wxPGProperty property,
wxWindow ctrl 
) const
pure virtual

Sets value in control to unspecified.

virtual void wxPGEditor::UpdateControl ( wxPGProperty property,
wxWindow ctrl 
) const
pure virtual

Loads value from property to the control.
