SelectionMargin OpenTool

Overview

The SelectionMargin OpenTool is an add-on for the Borland JBuilder IDE. It adds a selection margin to the left of each editor pane which has special selection behavior that is mostly the same as Microsoft Word. It allows you to easily select whole lines and therefore makes it easier to copy, cut or delete whole lines. The selection margin is also used to display line numbers.

The light gray area left to the editor pane is the selection margin. This picture shows a split view.

This OpenTool works together with the TextDragDrop OpenTool. It allows you to drop text onto the selection margin. The dropped text will be inserted at the beginning of the line.

Usage

When the mouse pointer is moved into the selection margin, it changes to a select arrow that points up and to the right (a mirror image of the standard select arrow).

• Click in the margin to select the entire line to the right of the mouse pointer.
• Click in the margin and move the mouse pointer to select multiple consecutive lines.
• While holding down SHIFT, click in the margin and move the mouse pointer to extend a selection.
• While holding down CTRL, click anywhere in the margin to select the entire file. (This is equivalent to choosing the Select All command from the Edit menu.)

Configuration

You can enable/disable the line number display in the Editor Options dialog.

A faster way to toggle the line number display is the popup menu of the selection margin. Right-click into the selection margin to get it.
