Lock Column width in #ListIconGadget
Posted: Thu Dec 20, 2007 5:08 pm

Aside from constantly checking the sizes of each column gadget in my program to insure that the user has not resized them... and then forcing them back to size...
Is there any way to just LOCK the column widths?

Code: Select all
Procedure WindowCallback(hWnd,uMsg,wParam,lParam)
Select uMsg
Case #WM_NOTIFY
*lpnm.NMHDR = lParam
If *lpnm\hwndFrom = GetWindow_(GadgetID(0),#GW_CHILD) And *lpnm\code = #HDN_BEGINTRACK
ProcedureReturn 1
EndIf
EndSelect
ProcedureReturn #PB_ProcessPureBasicEvents
EndProcedure
OpenWindow(0,0,0,320,240,"void",#PB_Window_SystemMenu | #PB_Window_ScreenCentered)

@fluid byte, works fine but won't irritate the user nearly enough. Try this:
Code: Select all
OpenWindow(0,0,0,320,240,"void",#PB_Window_SystemMenu | #PB_Window_ScreenCentered)
CreateGadgetList(WindowID(0))
ListIconGadget(0,0,0,320,240,"Name",160)
AddGadgetColumn(0,1,"Type",80)
AddGadgetColumn(0,1,"Size",60)
header = SendMessage_(GadgetID(0),#LVM_GETHEADER,0,0)
Repeat
ev = WaitWindowEvent(1)
GetWindowRect_(header, @wr.rect)
If PtInRect_(wr, DesktopMouseX(),DesktopMouseY())
ShowWindow_(header, #SW_HIDE)
dc = GetDC_(GadgetID(0))
TextOut_(dc, 100,0, PeekS(?begin), 15)
ReleaseDC_(GadgetID(0),dc)
Else
ShowWindow_(header, #SW_SHOW)
EndIf
Until ev = #WM_CLOSE

Altough I was laughing hard netmaestros way has a flaw. It prevents header dragging and sorting. If you really want insist in limiting your gadet this way you can directly use #LVS_NOCOLUMNHEADER.

That's the point: to stop the user changing the headers.

Keep going and we'll promote you to cane toad!
BTW, I didn't realise you could use PtInRect this way: PtInRect_(handle, x, y). My SDK says:
Code: Select all
BOOL PtInRect(
CONST RECT *lprc, // rectangle
POINT pt // point
);

If fangs likes it it must be truly perverted
@dare, yes the sdk is wrong on this doc. the function expects separate values for the x and y instead of a pointer to a point structure.

Thanks for the info mate.
BTW, if fangs likes it you probably need to go seek some professional help.
