Change color of say when mouse is over it

[Dietmar Jahnel]

Antonio,
is there a way to change the color of the text of a say-object when the mouse is moved over it and the cursor changes to HAND?

I did this for years with an old class called sensitive say:

Code: Select all  Expand view

REDEFINE SENSITIVE SAY geSay2 ID 903 of SuchFolder:aDialogs[2];
         COLOROVER RGB( 128, 0, 0 );
         BOX TRANSPARENT;
         ACTION (HelpTopic(IDH_SM_CHECK))
 

But now in Vista the transparent painting with this old class does not work any more.

Thanks for help,
Dietmar

Hello Dietmar,
you could try with lWantClick.
Best regards,
Otto

Code: Select all  Expand view

   oSay:lWantClick := .t.
   oSay:bMMoved   = {||oSay:SetColor(  0, RGB(128,128,255) ),   oSay:refresh() }

   oSay:lWantClick := .t.
   oSay:bMMoved   = {||oSay:SetColor(  0, RGB(128,128,255) ),   oSay:refresh() }

Sorry, but the color does not change...

Dietmar,
what version of FW do you use?
Do you have this line in Say class:

METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TSay

if ... nMsg == WM_NCHITTEST ) // To have a standard behavior on Clicks

Best regards,
Otto

Dietmar,
what version of FW do you use?

latest: 9.04

Do you have this line in Say class:

METHOD HandleEvent( nMsg, nWParam, nLParam ) CLASS TSay

if ... nMsg == WM_NCHITTEST ) // To have a standard behavior on Clicks

yes.
Do you get the color change?

Hello Dietmar,
yes. As soon as you move the mouse on the control the event is fired and it works.
I only don’t know – there are many ways – what would be the best way and when to change the color back to the original.
I have version 9.02 but I don’t think there was another change in the class.
Best regards,
Otto

Code: Select all  Expand view

// A sample showing to to let a SAY accept Clicks events

#include "FiveWin.ch"
#define COLOR_BTNFACE       15
function Main()
   local oDlg, oSay, oCursor
   DEFINE CURSOR oCursor HAND
   DEFINE DIALOG oDlg
   @ 2, 2 SAY oSay PROMPT "Test"
   oSay:lWantClick = .t.
   oSay:bMMoved   = {|| oSay:SetColor(  0, RGB(128,128,255) ),   oSay:refresh() }
   oSay:oCursor    = oCursor

   ACTIVATE DIALOG oDlg CENTERED

return nil

Not very elegant, but this works.

Code: Select all  Expand view

#include "urllink.ch"

.....
< other code >
 
@   40, 20 URLLINK oSay URL 'This is a say' ;
      PIXEL OF oWnd CLROVER CLR_HRED FONT oFont

<other code>

 

Probably a better way would be to derive a class from TUrlLink, with more features for mouseover, like change of font, change of background and foreground colors, attach an action block on click, etc. Or write a class derived from TSay with similar features
