Synopsis

          listbox listbox \
             items

Description

There is no justify for a listbox. This function can be called for windows of class: listbox, rtl_mlistbox, tablelist, hugelist. Only »listbox« windows are allowed here. The composed classes are processed later –rtl_mlistbox using listboxes; or are implemented as text windows –tablelist–, or canvas –hugelist.

The Internal size is somewhat smaller: borderWidth, highlightThickness, the viewport must be adjusted for this values, or rather clipping has to be defined. state, disabledForeground and foreground, cursor are needed, too.

Items are combined into a single text paragraph and passed on as a text object; the code generation coords are identified via x1..y2

Selection: • Draw select rectangles. • Use selectforeground for the selected items.

The coords inside a listbox must be integer, otherwise the text and rectangle alignment will get out-of-sync.

Added rectangles for each item, unselected items are classed as itemodd or itemeven, while selected items are classed as itemselect. –Allows for AQUA-Style alternating backgrounds via CSS.

Example 4.21. CSS Alternate Color for Listbox

rect.itemodd {
fill: #edf3fe;
fill-opacity: 1.0;
}
