Antonio, Example colors and themes

[Giovany Vecchi]

Hello Antonio. I made the color management example I have.
Initially I started doing these routines with the purpose of creating a class to manage themes. The logic is easy to understand.
In this class I use only 3 themes, but it could have infinite themes already registered. The challenge now is the parameterization of all controls (Ribbon, xBrowse, DataPick etc) and I believe that with this example I am posting it will serve as a basis for fivewin to obtain these routines in the future.
For now the controls call is only in the tDialog class. It would have to call from the tWindow classes for windows to parameterize the controls in it.
Attached is an example with the sources:

I see that comboboxes are not themed. I would like to know how do you set a background color for themed comboboxes, as in your example below, please:

[Giovany Vecchi]

Hi Enrico. In combobox I have 2 ways to apply the colors:
1-Apply without removing the characteristics of Themed
2-Apply removing the characteristics of Themed
In mode 1 only the combobox body is shown in color.
In mode 2 every combobox is displayed

Download the example I posted and see the sources.

Very good my dear friend. Super many thanks.

Hello Giovanny,
Impressive- Respect!

I'm interested in mode 1. But I don't understand what is the relevant code. I only need to color comboboxes background. Is there a simple way?

Master Enrico:

Code: Select all  Expand view

ACTIVATE DIA... ;
   ON INIT(  CTRLS_COLORS_DLG( oDlg ) )
 

Code: Select all  Expand view

   FUNCTION CTRLS_COLORS_DLG(f_oDlgContainer)

Dear Giovany,

Many thanks!

I have saved a copy here:

It doesn't work for me. The dropdownlist part of the comboboxes is colored but the select item is not. What am I doing wrong?

[Enrico Maria Giordano]

This is my sample (to compile with theme manifest):

Code: Select all  Expand view

#include "Fivewin.ch"


FUNCTION MAIN()

    LOCAL oDlg

    LOCAL cVar := ""

    DEFINE DIALOG oDlg

    @ 1, 1 COMBOBOX cVar;
           SIZE 100, 13;
           ITEMS { "Test1", "Test2", "Test3" }

    ACTIVATE DIALOG oDlg;
             ON INIT ( COLOR_SYS_INIT( 1, .F., .F., 1, 0 ),;
                       CTRLS_COLORS_DLG( oDlg ) );
             CENTER

    RETURN NIL

[Giovany Vecchi]

Hello Enrico, put option 2 in the parameter
COLOR_SYS_INIT( 1, .F., .F., 2, 0 )

The COLOR_SYS_INIT function is called only once at startup.
To select the theme colors in some control that you want to use differently, you create a variable object ex:

Code: Select all  Expand view

   Local oColorSys := COLOR_SYS_OBJ()
 
   Redefine Say id 100 Prompt "Testando" color oColorSys:nClrStaticTextCharBG, oColorSys:nClrBackGround

 

[Enrico Maria Giordano]

With option 2 the combobox is not themed. I want it themed. Can you change my sample to set the background color of a themed combobox? Is it possible at all?

[Giovany Vecchi]

Enrico I tried every way and I couldn't. This also happens with RadioButtons and CheckBox.
Windows assumes the control appearance and I haven't found a way to change this.

Master Enrico, simple example. Continue... Get the other functions from Giovanny's class, and test them. Your imagination is your limit.

Code: Select all  Expand view

#include "Fivewin.ch"

FUNCTION Main()

   LOCAL oDlg, oCbx, oSayItem, oSayAt, oFont
   LOCAL cItem := ""
   LOCAL aRect := {}

   SET _3DLOOK ON

   DEFINE FONT oFont NAME "TAHOMA" SIZE 0, - 20

   DEFINE DIALOG oDlg TITLE "Test ComboBox Witn Color" FROM 110, 1 TO 450, 600 ;
      PIXEL FONT oFont COLOR CLR_BLACK, CLR_WHITE TRANSPARENT

   oDlg:lHelPicon := .F.

   @ 10, 10 COMBOBOX oCbx VAR cItem ITEMS { "Testing", "this", "ComboBox" }  ;
      SIZE 200, 460 OF oDlg PIXEL HEIGHTGET 50

   ACTIVATE DIALOG oDlg CENTERED ;
      ON INIT( CTRLS_COLORS_DLG( oDlg ) )

   oFont:End()

Enrico I tried every way and I couldn't. This also happens with RadioButtons and CheckBox.
Windows assumes the control appearance and I haven't found a way to change this.
I'm now leaving it to the forum experts

Ok, I was afraid of that. Thank you anyway. Only, I don't understand your example image: I see two themed comboboxes with different background color, or am I wrong?
