TGTextEditor
A simple text editor that uses the TGTextEdit widget.
It provides all functionalities of TGTextEdit as copy, paste, cut,
search, go to a given line number. In addition, it provides the
possibilities for compiling, executing or interrupting a running
macro.
This class can be used in following ways:
- with file name as argument:
new TGTextEditor("hsimple.C");
- with a TMacro* as argument:
TMacro *macro = new TMacro("hsimple.C");
new TGTextEditor(macro);
Basic Features:
New Document
To create a new blank document, select File menu / New, or click
the New toolbar button. It will create a new instance of
TGTextEditor.
Open/Save File
To open a file, select File menu / Open or click on the Open
toolbar button. This will bring up the standard File Dialog for
opening files.
If the current document has not been saved yet, you will be asked
either to save or abandon the changes.
To save the file using the same name, select File menu / Save or
the toolbar Save button. To change the file name use File menu /
Save As... or corresponding SaveAs button on the toolbar.
Text Selection
You can move the cursor by simply clicking on the desired location
with the left mouse button. To highlight some text, press the mouse
and drag the mouse while holding the left button pressed.
To select a word, double-click on it;

A subsequent paste operation will insert the contents of the

location according to the selection made of a case sensitive mode
or not. The last search can be repeated by pressing F3.

area.
