[Demo] Plain-text checkboxes

Post by Sergey Tkachenko »

This demo shows how to implement checkboxes in TRichViewEdit using plain text.
No controls or images are used inside the editor in this demo: check marks are implemented as Unicode characters. Checkboxes are implemented as hyperlinks.

This demo has methods:

Code: Select all

    // gets the checkbox value
    function GetCheckBoxValue(const CheckBoxName: String): Boolean;
    // sets the checkbox value
    procedure SetCheckBoxValue(const CheckBoxName: String; Value: Boolean);
    // occurs when a checkbox is clicked
    procedure CheckBoxClickInEditor(const CheckBoxName: String; Checked: Boolean);
It shoes how to synchronize checkboxes in the editor and a group of TCheckBox controls.

This document can be stored not only in RVF but also in RTF.
Only one additional setting is needed to make checkboxes work after reloading from RTF: RichViewEdit1.RTFReadProperties.BasePathLinks = False. With this settings, hyperlink targets are saved and loaded as they are.
