Hello,

Has anyone successfully used CSS with XbpHTMLWindow?  I have tried the
following approach and the object is successfully created, but when
the dialog window is shown I get a runtime error in the
XbpHTMLStyle:draw() method (error log text below):

***** this code is from one of the XPP help topics
cCSS := ".mystyle { color: #ee99aa; }" +;
            ".mystyle:hover { color: #ff0000; }"

oStyle := XbpHTMLStyle():New( cCSS )
oStyle:MinHeight := 52

cHTML := '<p class="mystyle">My fancy HTML text</p>'

***** this is my code
oHtm := XbpHTMLWindow():new()
oHtm:HTML := cHTML
oHtm:VisualStyle := oStyle 
oHtm:create(...)  

oDlg:show()    Crash!

Note: On screen the XbpHTMLWindow object appears correctly with the
text "My fancy HTML text", but then the error msg box appears.

Error log:

This may be the wrong approach.  If anyone has done this can you show
some sample code?  Thanks very much.

Hi Clayton,

I'm just taking an educated guess.

I would try it this way (I would think you would have to target the 
class within oStyle ) -

oStyle:mystyle:MinHeight := "52px"

Note I have not used XbpHTMLStyle

Kind Regards,
Nestor
