Window style attributes: Basics

Basic presentation style attributes for window elements.

Style attributes listed in this page are general and supported on several front-end types, when the platform allows it. See also other pages about window style attributes.


Defines the default color used for TTF icons.

All TTF icons displayed in the window using this style get the color specified in the attribute.

The value for this attribute must be an RGB specification or a named color as listed in Colors.

For more details about TTF icon usage see Using a simple image name (centralized icons).


Indicates if the window content must be initialized with the saved positions and sizes. By default, windows are reopened at the position and with the size they had when they were closed. You can force the use of the initial settings with this attribute. This applies also to column position and width in tables.

Values can be "yes" or "no" (default).


Indicates the initial position of the window.

Values can be:
  • "default" (default): the windows are displayed depending on the window manager or browser rules.
  • "field": the window is displayed below the current field (works as "default", when current field does not exist). The windowType style attribute must be "modal". For more details, see Field-anchored picklist.
  • "center": the window is displayed in the center of the screen.

For front-ends using stored settings, "field" and "previous" have higher priority than the stored settings.


Defines if the window can be resized by the user.

Values can be "yes" (default), "no" or "auto".

  • On a normal window, the behavior is applied to the form instead of the window. When set to "no", the form content is not stretched, even if the form contains stretchable items.
  • On a modal window, when set to "no", the end-user cannot resize the modal window.

tabbedContainer (deprecated)

Important: tabbedContainer will be deprecated and replaced by a new style attribute.

Values can be "yes" or "no" (default).

When a window of an application uses tabbedContainer=yes, every application except the one hosting the tabbed container is embedded in a tab container.

When using this style attribute, the front-end sidebar is replaced by the StartMenu, which is mandatory when tabbedContainer=yes.

See also Containers for program windows.


Defines the display time (in seconds) of the automatic scrollbar displayed when scrolling on fixed screen array (a.k.a. "Matrix") and SCROLLGRIDs. After the delay, the scrollbar disappears.

A value of zero specifies an infinite time: The thin scrollbar remains visible while the record list can be scrolled (during dialog execution).

A negative value specifies that the scrollbar must always be hidden.

Default is 1 second.


Indicates the position of the toolbar, when a toolbar is defined.

Values can be one of:
  • "top" (default): Toolbar is displayed at the top of the window.
  • "bottom": Toolbar is displayed at the bottom of the window.
  • "none": The toolbar is not displayed.
  • "chrome": Action views are displayed in the frame of the browser surrounding the HTML content. See Action views in chromebar.


Defines if the window can be closed with a system menu option or window header button.

Values can be "yes", "no" or "auto" (default).

When value is "auto", the option is enabled depending on the window type.

This attribute may have different behavior depending on the front-end operating system. For example, when no system menu is used, it may not be possible to have this option enabled.


Defines the basic type of the window.

Values can be:
  • "normal" (default): Normal windows are displayed as typical application windows.
  • "modal": Modal windows are displayed over all other windows, typically used for temporary dialogs.
