SAY default background color

[James Bott]

Antonio,

I think that the background color of SAYs are not defaulting properly. This is from TSay:Redefine():

Code: Select all  Expand view  RUN

   DEFAULT oWnd      := GetWndDefault(),;
           nClrText  := oWnd:nClrText,;
           nClrBack  := GetSysColor( COLOR_BTNFACE ),;

nClrText is fine, but nClrBack is defaulting to the default dialog color. This works as long as you are putting the SAY on dialog with the default color, but not if the dialog has a different color than the default. I suggest that it should be:

nClrBack := oWnd:nClrBack

The TSay:New() method is different still.

Code: Select all  Expand view  RUN

          nClrBack := iif(Upper( oWnd:Classname() ) != "TWINDOW",;
                           GetSysColor( COLOR_BTNFACE ),;
                           oWnd:nClrPane),;

This defaults to the background color of it's parent but only if the parent is a TWindow. If not putting the SAY on a Window it defaults to the default dialog color which has the same problem as above. So I suggest always defaulting the background color of the SAY to it's parent's background color.

nClrBack := oWnd:nClrBack

However, since these days we are doing more with fancy graphics like putting bitmaps on windows and dialogs, etc., so it seems it would be better if SAYs always defaulted to transparent so they would always show the background of the parent even if it was a bitmap. This behavior would make the default color moot. Perhaps there is some reason this can't or shouldn't be done?

James,

Have you tried those proposed changes and see if they work fine ?

The issue about transparency is that Windows does not provide such feature, and we need to do it programmatically.

I'll do some testing and report back.

Antonio,

I tested the suggested revised default colors for both TWindow and TSay and I didn't see any problems. These changes would make Says appear to be transparent on any colored object (window, dialog, messagebar, etc) because they will always inherit the background color of the SAYs parent object.

My test code is below.

They would still not be truely transparent since they would not have a transparent background when drawn over a bitmap. After the next version of FWH comes out, I will work on testing SAYs that are truely transparent by default.

James
