Configuring windows with styles
Use the STYLE
attribute to set a style for a window.
The window style defines the type of the window (normal, modal) and its decoration, via the presentation style attribute. The presentation style specifies a set of attributes in an external file (.4st).
By default, windows are displayed as regular (normal) application windows. The type of window is
defined by the windowType
style attribute.
There are different ways to define the style of a window: The STYLE
can be used in the OPEN WINDOW
instruction to
define the default style for a window, or it can be specified in the form file, with the WINDOWSTYLE
attribute of the
LAYOUT
section.
In GUI mode, form elements can also be decorated with presentation styles. Pay attention to the specific rules that apply when combining TTY attributes and presentation styles.
Style name in 4st file | Description |
---|---|
Window |
Defines presentation attributes for regular application windows. |
Window.main , Window.main2 |
Defines presentation attributes for starter applications, where the main window shows a start menu if one is defined by the application. |
Window.dialog , Window.dialog2 ,
Window.dialog3 , Window.dialog4 |
Defines presentation attributes for modal windows. |
Window.naked |
Defines presentation attributes for windows that do not show the default view for ring menus and action buttons (OK/Cancel). |
Window.viewer |
Defines presentation attributes for viewers as the report pager (fglreport.per). |
It is recommended that you not change the default settings of windows styles in the $FGLDIR/lib/default.4st file. If you create your own style file, copy the default styles into your own file in a different directory.
It is not possible to change the presentation style attributes of windows dynamically in the AUI tree. The style is applied when the window and form are loaded.
If you open and display a second form in an existing window, the window style of the second form is not applied.
