(Versuch) TreeGadget + ListIconGadget = TreeListGadget

Beitrag von CNESM »

Hallo,

für ein kleines Projekt habe ich ein Gadget benötigt, das sich etwa aus einer Kombination von TreeGadget + ListIconGadget beschreiben lässt. Herausgekommen ist folgender Code:

Code: Alles auswählen

Procedure GetHeaderHeight(GadgetID.l)
  Header.RECT
  GetWindowRect_(SendMessage_(GadgetID(GadgetID.l) , #LVM_GETHEADER , 0 , 0) , Header)
  ProcedureReturn Header\bottom - Header\top
EndProcedure

Procedure WindowCallBack(Window ,  message ,  wParam ,  lParam)
  Protected wWidth.l ,  wHeight.l ,  Gadget_ID.l ,  AktColumn.l ,  LastColumn.l  
  Protected *pnmtv.NM_TREEVIEW
  ReturnValue  =  #PB_ProcessPureBasicEvents  
  Select message   
    Case #WM_NOTIFY  
      *nmHEADER.HD_NOTIFY = lParam  
      Gadget_ID = *nmHEADER\hdr\hwndFrom  
      Select *nmHEADER\hdr\code  
        Case #HDN_ITEMCHANGING ; is header item changing?  
          Select GetParent_(Gadget_ID)  
            Case GadgetID(2) 
              If *nmHEADER\iItem = 0
                Width.l = GetGadgetItemAttribute(2 ,  - 1 , #PB_ListIcon_ColumnWidth , 0)
                ResizeGadget(8 , Width.l , #PB_Ignore , 300 - Width.l , #PB_Ignore)
                ResizeGadget(0 , #PB_Ignore , #PB_Ignore , 300 - Width.l , #PB_Ignore)
                ResizeGadget(1 , #PB_Ignore , #PB_Ignore , Width.l , #PB_Ignore)
              ElseIf *nmHEADER\iItem = 1
                ReturnValue  =  #True  
              EndIf  
          EndSelect  
      EndSelect 
      *pnmtv = lParam
      Select *pnmtv\hdr\code
        Case #TVN_ITEMEXPANDED
          TreeListGadgetItem  =  *pnmtv\itemNew\lParam
          Select *pnmtv\action
            Case 1
              TreeListGadgetItemExpanded = 1
            Case 2
              TreeListGadgetItemExpanded = 2
          EndSelect
      EndSelect
  EndSelect  
  ProcedureReturn ReturnValue  
EndProcedure  

Procedure TreeListGadget_AddItem(Position.l , Text1.s , Text2.s , ImageID1.l , ImageID2.l , SubLevel.l)
  AddGadgetItem(1 , Position.l , Text1.s , ImageID1.l , SubLevel.l)
  AddGadgetItem(0 , Position.l , Text2.s , ImageID2.l , SubLevel.l)
EndProcedure

Procedure TreeListGadget_DeleteItem(Position.l)

Wahrscheinlich werden einige ihre Arme über den Kopf zusammenschlagen, aber vielleicht hat der ein oder andere ja Lust, das ganze noch etwas anzupassen bzw. zu erweitern.

hmm, gute Idee, aber bei mir ist die Spalte "Name" koplett grau, was sollte da stehen ?
Wenn da die Namen stehen sollten, denn sind diese nicht zu sehen.

Versuch mal den Code. Hab jetzt mal den Enable-Befehl rausgenommen:

Re: (Versuch) TreeGadget + ListIconGadget = TreeListGadget

Beitrag von hjbremer »

interessant, aber noch Optimierungs Potenzial

vor allem fehlt

Code: Alles auswählen

Global TreeListGadgetItemExpanded
oder zumindest ein shared im Callback

und ev. auch noch

Code: Alles auswählen

Global TreeListGadgetItem
aber das blick ich noch nicht. Ein paar Infos wären nicht schlecht

Hi, so interessant wie es ist, aber so wie es ist, blickt keiner bzw. ich nicht durch !

zuerst sollten alle Gadgets aussagekräftige Konstentennamen bekommen und dann die SetWindowLong Befehle kommentieren. Ich wette in 6 Monaten blickst du da selber nicht mehr durch.

Die ResizeGadget Befehle im Callback funktionieren scheinbar nicht richtig. Ebenso das Scrollen.

Aus zeitlichen Gründen habe ich mir das Nicht-Kommentieren angewöhnt.

Das der Code sehr unsauber ist, liegt auch daran, das ich mir ehrlich gesagt nicht die Arbeit gemacht habe, das alles ordentlich runterzuschreiben. Warum? Weil ich der meinung bin, das an diesem Konzept noch stark gearbeitet werden muss und daher eh noch enorm viele Anpassungen notwendig sind.

Hier mal eine andere Version:
