CSS
The visual appearance of BUI controls is defined using CSS (cascading style sheets) rules. Easily change the default colors, border, and other settings by customizing these rules, all without changing any application code. See CSS API for a high-level overview of BUI CSS.
For a BBjFontChooser sample program, refer to (demo, code). The BBjFontChooser defines the following style names:
.BBjChooser
.BBjFontChooser
.BBjFontChooser.bbj-disabled
.BBjFontChooser-familyPanel
.BBjFontChooser-familyLabel
.BBjFontChooser-familyText
.BBjFontChooser-familyList
.BBjFontChooser-stylePanel
.BBjFontChooser-styleLabel
.BBjFontChooser-styleText
.BBjFontChooser-styleList
.BBjFontChooser-sizePanel
.BBjFontChooser-sizeLabel
.BBjFontChooser-sizeText
.BBjFontChooser-sizeList
.BBjFontChooser-preview
.BBjChooser-button-panel
.BBjChooser-button
.BBjChooser-approveButton
.BBjChooser-cancelButton
Remarks
If the ID parameter is not specified, a control ID is assigned dynamically using getAvailableControlID().
If the x, y, width, and height parameters are not specified, they are all initialized to 0. This is typically for use with DWC windows that dynamically arrange their contents (window creation flag $00100000$).
