TGTextEditor Class Reference

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:

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; to select the text line - triple-click on it; to select all do quadruple-click.

Cut, Copy, Paste

After selecting some text, you can cut or copy it to the clipboard. A subsequent paste operation will insert the contents of the clipboard at the current cursor location.

Text Search

The editor uses a standard Search dialog. You can specify a forward or backward search direction starting from the current cursor location according to the selection made of a case sensitive mode or not. The last search can be repeated by pressing F3.

Text Font

You can change the text font by selecting Edit menu / Set Font. The Font Dialog pops up and shows the Name, Style, and Size of any available font. The selected font sample is shown in the preview area.

Executing Macros

You can execute the currently loaded macro in the editor by selecting Tools menu / Execute Macro; by clicking on the corresponding toolbar button, or by using Ctrl+F5 accelerator keys. This is identical to the command ".x macro.C" in the root prompt command line.

Compiling Macros

The currently loaded macro can be compiled with ACLiC if you select Tools menu / Compile Macro; by clicking on the corresponding toolbar button, or by using Ctrl+F7 accelerator keys. This is identical to the command ".L macro.C++" in the root prompt command line.

Interrupting a Running Macro

You can interrupt a running macro by selecting the Tools menu / Interrupt; by clicking on the corresponding toolbar button, or by using Shift+F5 accelerator keys.

Interface to CINT Interpreter

Any command entered in the Command combo box will be passed to the CINT interpreter. This combo box will keep the commands history and will allow you to re-execute the same commands during an editor session.

Keyboard Bindings

The following table lists the keyboard shortcuts and accelerator keys.

Key: Action

Ctrl+H Delete character before cursor, or text selection.
Ctrl+K Delete characters from current position to the end of line.
Ctrl+U Delete current line.
