Two aspects:
- Get the background color that is used in your application
I retrieve the color from the .ini file. You could also use $windowproperties to get the backcolor of the window. - Set the background color of the HTML using JavaScript.
The use of the eval function means that you do not have to include a JavaScript function in your HTML, meaning you can even use this for external websites.
; Set background color of the HTML widget to
; the color specified in the backcolor property of
; the window logical widget in
; the [application] section of the .ini file
call lpGetSetting("application\window","backcolor",vColor)
if (vColor <> "")
show
$fieldhandle("TEXT.DUMMY")->$widgetoperation( "JS:eval(%%"document.body.style.backgroundColor = '%%vColor%%%';%%")")
endif
