DH_TextIO

Function:

Multiline text input/output module with dynamically adjustable background and text colors and selection of fonts.

Panel Text Input/Output Display:

The text area where text is entered and displayed provides a minimal set of editing functions. The Backspace key, and keyboard shortcuts Ctrl-C (Copy), Ctrl-X (Cut), and Ctrl-V (Paste) are supported. The right-click menu options of Undo, Cut, Copy, Paste, Delete, and Select All are also available.

Inputs:

Load      Loads or reloads the input from the Text In pin to the display. Bool pin activates on change from TRUE to FALSE (mouse up).

Clear    Clears the display. Boolean pin activates on change from  TRUE to FALSE (mouse up).

Bkgd RGB    RGB value of background color.

Text RGB     RGB value of text color.

Font    List of 11 widely distributed fonts.

Font Size   List of selected font sizes.

Deferred Input    When TRUE, text input on the Text In pin is not displayed until the Load input is activated.

Read Only  When TRUE, prevents typing in the text area

Text I/O  (Right or left side)   Text to be displayed.

Outputs:

Text I/O  (Right or left side)   Outputs any text loaded or entered.

# Chars   The number of characters currently displayed.

Notes:

All of the pins are the newer "blue background" types, so that the module can easily be integrated with other sub-controls. The file DH_Controls_demo.se1 shows an example of this module being used in conjunction with other SynthEdit and DH sub-controls.

DH_TextIO supports 2-way flow, i.e., it will propagate changes either left to right or right to left.

An example of a momentary contact button that outputs a Boolean value suitable for use with the Load and Clear pins is included in the distribution .zip file as BoolButton.se1

The RGB values for background and text colors are easily obtained from DH_ColorPicker, or TextToRGB modules.

The listed fonts were selected because they are fairly standard for Windows systems. I chose a fixed list, rather than using a standard font chooser dialog that lists all of the fonts on the system, in order to give you, the designer, more control over the appearance of your VST/VSTi. If a selected font is not found on  the user's machine, another font in the same family is substituted.
