This keyword is not expanded by Git which means it's not replaced with the correct revision value in the releases made using git-based scripts and it's confusing to have lines with unexpanded "$Id$" in the released files. As expanding them with Git is not that simple (it could be done with git archive and export-subst attribute) and there are not many benefits in having them in the first place, just remove all these lines. If nothing else, this will make an eventual transition to Git simpler. Closes #14487. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74602 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

/**

@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_BUTTON )
|
|
{
|
|
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 );
