Text Boxes - Elements - Hag GUI for Cobra

Example text boxes using the XP theme.

Textboxes are rectangular elements used for string entry.

Hag text boxes fully support the mouse for selecting text and most keyboard shortcuts including Ctrl+C, Ctrl+X, Ctrl+V, Ctrl+B (bold), Ctrl+I (italic), Ctrl+U (underline), Shift+Left/Right (selection), delete, selection replacement, etc.

All Hag text boxes are rich text (each character can be fully styled):

Example rich-text boxes demonstrating individual styling of letters.

Textboxes can also be used for password entry, displaying asterisks in place of input.

Textbox elements expose the following read-only variables:

textbox.x: Integer - Textbox x position
textbox.y: Integer - Textbox y position
textbox.w: Integer - Textbox width
textbox.h: Integer - Textbox height
textbox.enabled: Boolean - If textbox is enabled
textbox.visible: Boolean - If textbox is visible
textbox.password: Boolean - If textbox is for password entry
textbox.gotUpdated: Boolean - If textbox got updated

For a ready-to-run example, see Example_Textbox or Example2D in the Examples download.
