Ok, I was wrong about that KILL_FOCUS point, but I have worked out an example
of an array of symbolic SpinCtrls that might be a useful inclusion to the
example scripts:
function Main()
FRAME=wx.wxFrame(wx.NULL,-1,"")
FRAME:SetTitle("Symbolic SpinCtrl Array")
PANEL=wx.wxPanel(FRAME,-1)
IDS=wx.wxID_HIGHEST+1
-- IDS is 'ID Start', first ID of safe range unused by system.
NT={"One","Two","Three","Four","Five",
-- Creates a table of text representations to assist user input.
"Six","Seven","Eight","Nine"
} NT[0]="Zero"
SC={}
for N=1,4 do local ID=IDS+N
SC[N]=wx.wxSpinCtrl(PANEL,ID,"",wx.wxPoint(N*62-60,2),
-- Physical placement arithmetic done here to keep it simple.
wx.wxSize(60,20),wx.wxSP_ARROW_KEYS+wx.wxTE_PROCESS_ENTER,0,9,0
-- Note two 'styles' to enable arrow keys and direct text entry.
)
SC[N]:Connect(ID,wx.wxEVT_SCROLL_THUMBTRACK,FeedBack)
-- Acts as wxEVT_COMMAND_SPINCTRL_UPDATED once did, ALWAYS signals!
SC[N]:Connect(ID,wx.wxEVT_COMMAND_TEXT_ENTER,FeedBack)
-- Required, as is wxTE_PROCESS_ENTER, to enable direct number entry.
SC[N]:Connect(ID,wx.wxEVT_KILL_FOCUS,NoOp)
-- Prevents de-focus replacing text with lowest preset number value.
end
FRAME:SetSize(258,51) FRAME:Centre() FRAME:Show()
end
function FeedBack(I)
if type(I)=="userdata" then I=I:GetId()-IDS end
-- This test allows the function to be passed an event OR an index.
SC[I]:SetValue(NT[SC[I]:GetValue()])
-- Fetches value, indexes symbolic text to replace it for user display.
end
function NoOp() end
-- Does nothing! Called to prevent unwanted inbuilt event handling.
Main()
