Usage

• To use the class in your code simply include PushPin.cpp and PushPin.h in your project and #include "PushPin.h" in which ever of your modules needs to make calls to the class.
• You should also ensure that the 4 bitmaps (namely IDB_PP_PINNED, IDB_PP_PINNEDEDGE, IDB_PP_UNPINNED and IDB_PP_UNPINNEDEDGE) are copied over into your rc file.
• Create a dialog template with an owner-draw button positioned where you want the push pin button. The size of the button in the template does not matter.
• Using Classwizard associate a CBitmap with the button you just created. Then modify the declaration of the variable to make it a CPushPinButton instead of CButton.
• To ensure that the class operates correctly when a color scheme change occurs, You should call the ReloadBitmaps() method in response to WM_SETTINGCHANGE or WM_WININICHANGE messages.
• Your code will need to include MFC either statically or dynamically.

History

V1.0 (7 December 1997)

• Minor code changes to fix a small redraw bug.

V1.01 (26 November 1997)

• Minor code changes to facilitate new CPushPinFrame module.

V1.1 (20 November 1997)

• Supports non default color schemes.
• Supports dynamic changes to color schemes.
• Complete restructuring of code.
• Can now use an edged bitmap if you want to.
• Dropped support for Win16.
• Redid the example program.
• Simplified external usage of class.

V1.11 (22 February 1999)

• A number of small code updates.
• Code now compiles cleanly at warning level 4.
• Code is now UNICODE enabled and build configurations are provided.

V1.12 (2 June 1999)

• Added a number of comments to improve code readability.
• Changed the resource id of the button bitmaps to more meaningful values.
• Class no longer uses message reflection to catch changes in the clicked state. This means that parent classes can now catch the clicked notification.
• Code now uses mouse capturing which means that the button appears pressed if you click and hold the left mouse button over the push pin. This gives the pushpin class this standard button behavior.

Planned Enhancements

• If you have any other suggested improvements, please let me know so that I can incorporate them into the next release.
