Display Resolution Regulator

What

• corp_n_cst_appmanager
• corp_n_cst_displaychange
  

Why

Resize service doesn't open the window occupying exactly same space even when opened in its original size if display settings are different. Also, it doesn't change the size if window is opened already in one settings and settings change.

How

• Add corpwsrv.pbl in your library path.
  
• Inherit n_cst_appmanager, w_frame and w_sheet from corp_n_cst_appmanager, corp_w_frame and corp_w_sheet resp. If you already have some code in any of these descendants you can export those descendants and replace references to existing ancestor with these new ancestors. Import these objects back. You can replace your descendant by copying descendants provided in this pbl. The ones that you don't want to copy and would like to inherit can be simply deleted from this pbl.
  
• To instantiate service, from your last descendant of n_cst_appmanager's constructor call this:
  

of_SetDisplayChange( TRUE)

• From pfc_pretopen of each sheet window that you want to be resizable like this call this :
  

If IsValid( gnv_app.inv_cst_displaychange) Then gnv_app.inv_cst_displaychange.of_register( this.ClassName(), 480,& 640) End If

Note : You still need resize service of your own. This service is not replacement to resize service, it is supplement to it. However, it is in no way related to PFC's resize service; so you may use resize code of your choice like resize from PowerBuilder Examples or even your own code.

• Also override pfc_postopen event and add following call at end:

super::Event pfc_postopen()

Note: You have to instantiate or register your resize service before this statement for it to work properly( this includes registering all your objects on screen that you want to be taken care of by resize).
