CustomTextCommand

CustomTextCommand is a sample that shows you how to write a derived class of a text command (in this case TReplaceTextCommand) and put your command into a menu. It overrides TReplaceTextCommand::HandleDoBegin to compute replacement text for the currently selected text. It also illustrates one way to use TTextChunkIterator.

Running the sample

Execute CustomTextCommandSApp. Select a few words of text and then issue the Scramble Text command from the menu. The selected text is replaced by the same text, but with the words in a different order.

Files and classes

TScrambleTextCommand, defined in ScrambleTextCommand.h and ScrambleTextCommand.C, derives from TReplaceTextCommand and overrides HandleDoBegin to initialize the text that replaces the current selection. For fun, it extracts the current text, scrambles the words, and uses that as the replacement text. It uses TTextRepresentationReadEntry to access the text and TTextChunkIterator to break the selection into TTextRanges.

CustomTextCommandMain.C shows how to use MMomentaryTextCommandState and TCommandOn to add a command to a menu.
