One of my customers contacted me couple of days ago to ask if it was possible to sort items in a drop button, when the items are created at runtime. Since the items are stored in a queue I figured it would be fairly easy. <\/p>\n

\n
\r\n Toolbar1.DeleteItems(ID1_Name)\r\n\r\n Toolbar1.AddDropItem(ID1_Name,'Arnor','ok_16.ico',1)\r\n Toolbar1.AddDropItem(ID1_Name,'Robert','ok_16.ico',2)\r\n Toolbar1.AddDropItem(ID1_Name,'Monica','ok_16.ico',3)\r\n Toolbar1.AddDropItem(ID1_Name,'Ana Maria','ok_16.ico',4)\r\n Toolbar1.AddDropItem(ID1_Name,'Ivan','ok_16.ico',5)\r\n\r\n Sort(Toolbar1.BandQ.ControlQ.pDropButton.ItemQ,|\r\n      Toolbar1.BandQ.ControlQ.pDropButton.ItemQ.szTxt)\r\n !! Reset the ItemIDs after sorting the queue.\r\n Loop I# = 1 To Records(Toolbar1.BandQ.ControlQ.pDropButton.ItemQ)\r\n   Get(Toolbar1.BandQ.ControlQ.pDropButton.ItemQ,I#)\r\n   Toolbar1.BandQ.ControlQ.pDropButton.ItemQ.ItemID = I#\r\n   Put(Toolbar1.BandQ.ControlQ.pDropButton.ItemQ)\r\n End\r\n Display()\r\n<\/pre>\n<\/div>\n
Note that this will not work properly if you have separators in the drop items.  If you want to do that, I would suggest to add the item text entries to a queue and sort them before you add them to the drop button.  Something like this might work:<\/p>\n
\n
\r\nAddDropButtonItems         ROUTINE\r\n Data\r\nQ   Queue\r\nT     CString(256) !! Item text\r\nSF    Byte         !! Separator Follows\r\n    End\r\n Code\r\n Q.T = 'Arnor' ;     Q.SF = False; Add(Q)\r\n Q.T = 'Robert' ;    Q.SF = True;  Add(Q)\r\n Q.T = 'Monica' ;    Q.SF = False; Add(Q)\r\n Q.T = 'Ana Maria' ; Q.SF = False; Add(Q)\r\n Q.T = 'Ivan' ;      Q.SF = False; Add(Q)\r\n Sort(Q,Q.T)\r\n Toolbar1.DeleteItems(ID1_Name)\r\n Loop X# = 1 To Records(Q)\r\n   Get(Q,X#)\r\n   Toolbar1.AddDropItem(ID1_Name,Q.T,'ok_16.ico',1)\r\n   If Q.SF = True !! Add Separator\r\n     Toolbar1.AddDropItem(ID1_Name,'-','ok_16.ico',1)\r\n   End\r\n End\r\n\r\n Display()\r\n<\/pre>\n<\/div>\n
This should be able to handle sorted list with separators.  I'm planning to add a method to sort the items alphabetically and I think I can make it handle the separators correctly too.  The method I describe here is a bit more flexible as it gives you full control over how the items are arranged.  <\/p>\n
