[SOLVED] (end)User Friendly Way to delete ListIconGadget line?

I have a populated listIconGadget() Where I would like to allow the user to select a line and press Delete to remove that line. Is there any way to do that without a callback? (What a Pain!) We can use the following for sample purposes:
Code: Select all
If OpenWindow(0, 100, 100, 300, 220, "ListIcon Example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ListIconGadget(0, 5, 5, 290, 200, "Name", 100, #PB_ListIcon_FullRowSelect | #PB_ListIcon_AlwaysShowSelection)
AddGadgetColumn(0, 1, "Address", 250)
AddGadgetItem(0, -1, "Harry Rannit"+Chr(10)+"12 Parliament Way, Battle Street, By the Bay")
AddGadgetItem(0, -1, "Ginger Brokeit"+Chr(10)+"130 PureBasic Road, BigTown, CodeCity")
AddGadgetItem(0, -1, "Harry Rannit"+Chr(10)+"12 Parliament Way, Battle Street, By the Bay")
AddGadgetItem(0, -1, "Ginger Brokeit"+Chr(10)+"130 PureBasic Road, BigTown, CodeCity")
AddGadgetItem(0, -1, "Harry Rannit"+Chr(10)+"12 Parliament Way, Battle Street, By the Bay")
AddGadgetItem(0, -1, "Ginger Brokeit"+Chr(10)+"130 PureBasic Road, BigTown, CodeCity")
Repeat
Select WaitWindowEvent()
Case #WM_KEYDOWN
Debug "KEY down"
If GetKeyState_(#VK_DELETE)
Debug "Yep!!!"
h.i = CountGadgetItems(0)
Debug h
If h > 3
h = h-1
For e.i = h To 0 Step -1
If GetGadgetItemState(0, e)
RemoveGadgetItem(0, e)
EndIf
Next e
EndIf
EndIf
EndSelect
Until Event = #PB_Event_CloseWindow
I figured out one way using combo of #WM_KEYDOWN and GetKeyState_(#VK_DELETE) as illustrated in the revised code above.

For Windows you can do it like below. Change #WM_KEYDOWN to #WM_KEYUP if you don't want the user to hold down the Delete key.
Code: Select all
If OpenWindow(0, 100, 100, 300, 300, "ListIcon Example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ListIconGadget(0, 5, 5, 290, 290, "Number", 100, #PB_ListIcon_FullRowSelect | #PB_ListIcon_AlwaysShowSelection)
For i=1 To 100
AddGadgetItem(0, -1, Str(i))
Next
Repeat
Event = WaitWindowEvent()
If Event = #WM_KEYDOWN And EventwParam() = #VK_DELETE
i = GetGadgetState(0)
RemoveGadgetItem(0, i)
SetGadgetState(0, i)
EndIf
Until Event = #PB_Event_CloseWindow
EndIf

Ok, Your way is much cleaner than the method I figured out above. Thanks BarryG

The same code, but cross platform :
Code: Select all
Enumeration
#KeyDelete
EndEnumeration
If OpenWindow(0, 100, 100, 300, 300, "ListIcon Example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
AddKeyboardShortcut(0, #PB_Shortcut_Delete, #KeyDelete)
ListIconGadget(0, 5, 5, 290, 290, "Number", 100, #PB_ListIcon_FullRowSelect | #PB_ListIcon_AlwaysShowSelection)
For i=1 To 100
AddGadgetItem(0, -1, Str(i))
Next
Repeat
Event = WaitWindowEvent()
If Event = #PB_Event_Menu And EventMenu() = #KeyDelete
i = GetGadgetState(0)
RemoveGadgetItem(0, i)
SetGadgetState(0, i)
EndIf
Until Event = #PB_Event_CloseWindow
EndIf

But then you can't use the Delete key in your app, such as when using a StringGadget.

You can chop and change shortcuts at will:
Code: Select all
Enumeration
#KeyDelete
EndEnumeration
If OpenWindow(0, 100, 100, 300, 500, "ListIcon Example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
ListIconGadget(0, 5, 5, 290, 290, "Number", 100, #PB_ListIcon_FullRowSelect | #PB_ListIcon_AlwaysShowSelection)
For i=1 To 100
AddGadgetItem(0, -1, Str(i))
Next
StringGadget(1, 5, 305, 290, 25, "Edit me!")
EditorGadget(2, 5, 335, 290, 100)
SetGadgetText(2, "And me too!")
Repeat
Event = WaitWindowEvent()
If GetActiveGadget() = 0
AddKeyboardShortcut(0, #PB_Shortcut_Delete, #KeyDelete)
Else
RemoveKeyboardShortcut(0, #PB_Shortcut_Delete)
EndIf
If Event = #PB_Event_Menu And EventMenu() = #KeyDelete
i = GetGadgetState(0)
If i > -1
RemoveGadgetItem(0, i)
SetGadgetState(0, i)
EndIf
EndIf
Until Event = #PB_Event_CloseWindow
EndIf

First, make sure that the item is selected.

That's a good point. There's a potential runtime error there, if you don't.

Very nice !
I double that. OKay then... Fred should put spikey's snippet into the Help doc under RemoveGadgetItem since there is no sample code there now. Yeah Yeah!! That would be great! Thanks Fred!!!
