List box Header Text Color not working

Trying to set back and text colors for listbox headers.

The Header Text uses Format() Modifier HT(color) which the Template generation does not correctly support.

Generation ignores the “H” and sees it as a Tree T(type) so adds a Level LONG to the Queue. The Format does not really have a TREE so that extra LONG is seen as a Color (you have * colors) and Zero is Black. Plus that extra column throws off all subsequent columns.

The only way to do in an APP it is NOT in the IDE but at runtime with PROPLIST: settings:

?Browse:1{PROPLIST:HdrBackColor,11} = Color:Red
?Browse:1{PROPLIST:HdrTextColor,11} = Color:White
?Browse:1{PROPLIST:HdrBackColor,12} = Color:Red
?Browse:1{PROPLIST:HdrTextColor,12} = Color:White

As you edit the LIST the column numbers change. So best not use use 11 and 12 instead use a Template to generate Equates like this one:

Template for generating Column and Group equates for ABC browse

I took Rick’s template for Generating Column Equates and added Equates for LIST Groups. Everything Rick said applies to Groups also. Instead of using hard-coded numeric constants for column numbers in code for manipulating your list control columns, it is better to use an equate for the column number. Hard-coded column numbers can become incorrect when new columns are added or columns deleted or reordered in the list format. Using the use equates means your code won’t need to be updated when t…

When you paste code (like your LIST) be sure to select it and press </> so it is formatted as CODE; otherwise, all your Quotes CHR(39) get changed to Typesetter quotes so the pasted code cannot be used.
