TRN
The TRN attribute (PROP:TRN) on a control specifies the characters print or display transparently, without obliterating the background over which the control is placed. This attribute is valid in Clarion Win32 Windows, and also for REPORT structures in both Clarion Win32 and Clarion#. Only the dots or pixels required to create each character are printed or displayed. This allows you to place the control directly on top of an IMAGE without destroying the background picture.
Example:
CustRpt REPORT,AT(1000,1000,6500,9000),THOUS
FORM,AT(0,0,6500,9000)
IMAGE('PIC.BMP'),USE(?I1)AT(0,0,6500,9000) !Full page image
!Transparent string on the image:
STRING('String Constant'),AT(10,0,20,20),USE(?S1),TRN
END
END
WinOne WINDOW,AT(0,0,160,400)
IMAGE('PIC.BMP'),USE(?I1),FULL !Full window image
!Transparent string on image
STRING('String Constant'),AT(10,0,20,20),USE(?S1),TRN
END
