WidgetMessage: tm-edit-text-operation

2024년 9월 9일 오전 8:35

A tm-edit-text-operation invokes one of the available operations on a surrounding text editor. Therefore the message has to be dispatched within the editor in order for it to catch it. The following properties on the event object are required:

Name	Description
param	Name of the operation to be executed, see below for a list of possible operations
{any other params}	Any other parameters are made available as variables within the context of the widget message.

The tm-edit-text-operation message is usually generated by a ButtonWidget or an ActionWidget and is handled by the surrounding text editor.
