Buttons
XStandard's toolbar is totally customizable. You can show/hide buttons from a list of predefined buttons or you can define your own buttons and even change their icons. The screen shot below shows XStandard toolbar with different grouping of icons.
The screen shot below shows custom icons in place of XStandard default icons.
Buttons on the toolbar can be used for multiple-purposes. Besides executing a predefined command such as bringing up a table or image dialog box, buttons can apply styles (similar to the styles found in the Styles drop-down list), insert code snippets or just generate an event that the parent application can hook into.
The buttons are defined in an XML document. An example of this document can be found at "C:\Program Files\XStandard\buttons.xml" on Windows, in "/Applications/XStandard/buttons.xml" on OS X or download buttons.xml. If no custom buttons XML file is specified, XStandard will use built-in buttons. The list of buttons to display on the toolbar, from the list of buttons defined in the XML document, is set through the following property:
<param name="ToolbarWysiwyg" value="ordered-list, unordered-list, definition-list,, draw-layout-table, draw-data-table, image, separator, hyperlink, attachment, directory, spellchecker,, wysiwyg, source, preview, screen-reader, help" />
The XML for button definition looks like this:
