Theme Schema File - 07/20/00
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
1. Description: the theme schema file is a "C" header file that uses special macros defined by
|
||
|
|
the file "SchemaDef.h"
|
||
|
|
|
||
|
|
2. The system schema file (for uxtheme.dll and comctl32.dll) is named "TmSchema.h".
|
||
|
|
|
||
|
|
3. Purpose: the schema file defines a common set of enums, properties, class parts, and class states
|
||
|
|
to be shared between the Theme Manager drawing/info routines, the theme authoring file, and the
|
||
|
|
theme-aware controls
|
||
|
|
|
||
|
|
4. File layout:
|
||
|
|
|
||
|
|
|
||
|
|
a. file start
|
||
|
|
- the first part of the file contains some fixed information:
|
||
|
|
|
||
|
|
//-----------------------------------------------------------------
|
||
|
|
#if (defined(SCHEMA_STRINGS)) || (! defined(TMSCHEMA_H))
|
||
|
|
//-----------------------------------------------------------------
|
||
|
|
#define TMSCHEMA_H
|
||
|
|
//-----------------------------------------------------------------
|
||
|
|
#include "SchemaDef.h"
|
||
|
|
//-----------------------------------------------------------------
|
||
|
|
#define THEMEMGR_VERSION 1 // increment if order of props changes or
|
||
|
|
// any props are deleted (will prevent loading
|
||
|
|
// of controlsets that use older version
|
||
|
|
//-----------------------------------------------------------------
|
||
|
|
BEGIN_TM_SCHEMA(xxx)
|
||
|
|
|
||
|
|
(where "xxx" is the schema name)
|
||
|
|
|
||
|
|
|
||
|
|
b. enums section
|
||
|
|
- this section contains one or more enum definitions
|
||
|
|
|
||
|
|
- each enum definition defines an enum name and a set of named values
|
||
|
|
|
||
|
|
- example:
|
||
|
|
|
||
|
|
BEGIN_TM_ENUM(BGTYPE)
|
||
|
|
TM_ENUM(BT, IMAGEFILE)
|
||
|
|
TM_ENUM(BT, BORDERFILL)
|
||
|
|
TM_ENUM(BT, NTLFILE)
|
||
|
|
END_TM_ENUM()
|
||
|
|
|
||
|
|
The above example declares an enum called "BGTYPE". It has 3 named
|
||
|
|
values: IMAGEFILE (value=0), BORDERFILL (value=1), and NTLFILE (value=2)
|
||
|
|
|
||
|
|
c. properties section
|
||
|
|
- this section defines a set of properties based on the primitive
|
||
|
|
property types or a previously declared enum
|
||
|
|
|
||
|
|
- section starts with the line:
|
||
|
|
BEGIN_TM_PROPS()
|
||
|
|
|
||
|
|
- section ends with the line:
|
||
|
|
END_TM_PROPS()
|
||
|
|
|
||
|
|
- example property:
|
||
|
|
|
||
|
|
TM_PROP(TMT, BORDERSIZE, INT)
|
||
|
|
|
||
|
|
(declares a "BorderSize" property of type "int")
|
||
|
|
|
||
|
|
|
||
|
|
- example property:
|
||
|
|
|
||
|
|
TM_PROP(TMT, BGTYPE, ENUM)
|
||
|
|
|
||
|
|
(declares a "BgType" property of type enum)
|
||
|
|
|
||
|
|
|
||
|
|
d. parts/states section
|
||
|
|
- this section contains one or more parts/states declarations
|
||
|
|
|
||
|
|
- example:
|
||
|
|
|
||
|
|
BEGIN_TM_CLASS_PARTS(BUTTON)
|
||
|
|
TM_PART(BP, PUSHBUTTON)
|
||
|
|
TM_PART(BP, RADIOBUTTON)
|
||
|
|
TM_PART(BP, CHECKBOX)
|
||
|
|
TM_PART(BP, GROUPBOX)
|
||
|
|
TM_PART(BP, USERBUTTON)
|
||
|
|
END_TM_CLASS_PARTS()
|
||
|
|
|
||
|
|
(the above defines a class called "button" that
|
||
|
|
has the 5 specified parts)
|
||
|
|
|
||
|
|
|
||
|
|
- example:
|
||
|
|
|
||
|
|
BEGIN_TM_PART_STATES(PUSHBUTTON)
|
||
|
|
TM_STATE(PBS, NORMAL)
|
||
|
|
TM_STATE(PBS, HOT)
|
||
|
|
TM_STATE(PBS, PRESSED)
|
||
|
|
TM_STATE(PBS, DISABLED)
|
||
|
|
TM_STATE(PBS, DEFAULTED)
|
||
|
|
END_TM_PART_STATES()
|
||
|
|
|
||
|
|
(the above defines a part called "pushbutton" that has
|
||
|
|
the 5 specified states)
|
||
|
|
|
||
|
|
e. file ending
|
||
|
|
|
||
|
|
- this section should look like:
|
||
|
|
|
||
|
|
END_TM_SCHEMA(xxx)
|
||
|
|
//---------------------------------------------------------------------------
|
||
|
|
#endif // TMSCHEMA_H
|
||
|
|
//---------------------------------------------------------------------------
|
||
|
|
|
||
|
|
(where "xxx" is the schema name)
|
||
|
|
|
||
|
|
|
||
|
|
5. The system schema file (TmSchema.h) is compiled into:
|
||
|
|
|
||
|
|
- uxtheme.dll (theme manager code)
|
||
|
|
|
||
|
|
- comctl32.dll (common controls code)
|
||
|
|
|
||
|
|
- packthem.exe (theme packaging utility)
|
||
|
|
|
||
|
|
- <theme-aware custom controls>
|
||
|
|
|
||
|
|
|
||
|
|
6. custom controls can define their own schema file that extend the system schema. This
|
||
|
|
schema file should be compiled into the control's DLL and the DLL should be registered
|
||
|
|
as "Path" values under the registry key:
|
||
|
|
|
||
|
|
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ThemeManager\CustomControls
|
||
|
|
|
||
|
|
example: Path = "c:\program files\acme\keypad.dll"
|
||
|
|
|
||
|
|
|
||
|
|
7. during theme packaging, the "packthem.exe" will attempt to call each registered DLL to get its
|
||
|
|
schema info. This call is automatically implemented when the schema file is built using the
|
||
|
|
format described in this document.
|
||
|
|
|
||
|
|
|
||
|
|
8. uxtheme.dll will also load registered control DLL's for the schema during every theme load
|
||
|
|
|
||
|
