/**

@class wxPGEditor
|
|
|
|
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:
|
|
@code
|
|
wxPGEditor* editorPointer = wxPropertyGrid::RegisterEditorClass(new MyEditorClass(), "MyEditor");
|
|
@endcode
|
|
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().

@class wxPGMultiButton

This class can be used to have multiple buttons in a property editor.

You will need to create a new property editor class, override CreateControls,

and have it return wxPGMultiButton instance in wxPGWindowList::SetSecondary().
|

|
|
For instance, here we add three buttons to a TextCtrl editor:

{
|

if ( event.GetEventType() == wxEVT_COMMAND_BUTTON_CLICKED )
|
|
{
|
|
wxPGMultiButton* buttons = (wxPGMultiButton*) propGrid->GetEditorControlSecondary();
|
|
|
|
if ( event.GetId() == buttons->GetButtonId(0) )
|
|
{
|
|
// Do something when the first button is pressed

Further to use this editor, code like this can be used:

|
|
@code
|
|
// Register editor class - needs only to be called once
|
|
wxPGEditor* multiButtonEditor = new wxSampleMultiButtonEditor();
|
|

|
|
|
|
// Insert the property that will have multiple buttons
|
|
propGrid->Append( new wxLongStringProperty("MultipleButtons", wxPG_LABEL) );
|
|
|
|
// Change property to use editor created in the previous code segment
|
|
propGrid->SetPropertyEditor( "MultipleButtons", multiButtonEditor );
