LD full-screen windows

Most users prefer running applications in a full-screen mode for easier handling and navigation.

There are three ways to make a mobile application run in full screen - by STYLE attribute, via a user theme, by specifying the last attribute for fgl_window_open().

STYLE attribute

To achieve the necessary result (to open window in full screen), add the style attribute to the 4gl code:

OPEN WINDOW w_name WITH FORM "form_name" ATTRIBUTE(BORDER, STYLE="full-screen")

where a STYLE attribute value full-screen stand for a class name that enables the full-screen mode.

User theme

 

Lycia Theme Designer allows 4gl developers to use special classes to adjust application layout, lycia_normal both for a desktop client or a browser (but not a mobile device) and lycia_desktop for the desktop client.

 

To achieve the necessary result (to open window in full screen), apply the full-screen class via the With class filter:

<StyleSheet xmlns="http://querix.com">   <ElementFilter ElementName="Application">     <StyleSheet>       <WithClassFilter ClassName="lycia_desktop">         <StyleSheet>           <ChildFilter>             <StyleSheet>               <ElementFilter ElementName="Window">                 <StyleSheet>                   <DoStyleAction>                     <ApplyClass Name="full-screen" />                   </DoStyleAction>                 </StyleSheet>               </ElementFilter>             </StyleSheet>           </ChildFilter>         </StyleSheet>       </WithClassFilter>     </StyleSheet>   </ElementFilter> </StyleSheet>

In the screenshot above, an application will open in full screen when run by LyciaDesktop.

fgl_window_open()

To open the window as a flat one and in full screen, set the last parameter to FALSE:

CALL fgl_window_open("w_test", 2, 2, "form_name", FALSE)

To open the window as a bordered one, set the last parameter to TRUE:

CALL fgl_window_open("w_test", 2, 2, "form_name", TRUE)
