Thanks for keeping it going. Got some trouble though.. For now I'll have to
stay with wxLua v2.8.7.0.
The new error reporting method doesn't work well. While I know someone asked
for it to print messages to the console, that's broken more than it fixed. Now,
if there's an error, the program exits, reporting nothing. (I launch scripts by
using WIndows to associate them with wxLua.exe. If I try launching them from a
commandline, nothing is reported there either, so I try launching them from
wxLua.exe directly. This is clumsy, drag/drop won't work as it does if I launch
by dragging to the file's icon in a directory (but that doesn't report errors
now). Dragging onto the pre-opened wxLua fails because it's not enabled for
drag/drop, so I must browse manually to the file. That fails too because it
doesn't recognise spaces in file names! This is definitely not an improvement.
While the script does open in wxLua, it won't run because even though it has it
opened, it can't actually FIND it by file name to run it. Please let us use our
OS's inbuilt tools to handle this stuff, it's a better way, usually, as it
works for everything we do with the OS as well. Right now we can't if we want
error reporting. (How about an option to send error reports to a file? That way
I can see them as before, in a message box, but also have a written copy if I
need one).
Another thing I have found is a failure in EVT_ERASE_BACKGROUND blocking. I'm
getting flicker in something that didn't flicker in the previous release of
wxLua. Note the two commented lines...
function Main()
FRAME=wx.wxFrame(wx.NULL,-1,"")
FRAME:CreateStatusBar() FRAME:SetStatusText(" ")
LAYER=wx.wxPanel(FRAME,-1) PANEL=wx.wxPanel(FRAME,-1)
CHART=wx.wxStaticBitmap(PANEL,-1)
FRAME:SetSize(800,600) FRAME:Centre() FRAME:Show(true)
BITMAP=wx.wxBitmap("Some Really Big Full Colour Bitmap.jpg")
BX,BY,OX,OY,PX,PY=BITMAP:GetWidth(),BITMAP:GetHeight(),0,0,0,0
CHART:SetBitmap(BITMAP)
FRAME:Connect(wx.wxEVT_SIZE,OnSize)
LAYER:Connect(wx.wxEVT_LEFT_DOWN,function(E) PX,PY=OX-E:GetX(),OY-E:GetY()
end)
LAYER:Connect(wx.wxEVT_MOTION,OnMotion)
LAYER:Connect(wx.wxEVT_ERASE_BACKGROUND,function() end)
PANEL:Connect(wx.wxEVT_ERASE_BACKGROUND,function() end) --Either of these
ought to stop flicker but don't.
CHART:Connect(wx.wxEVT_ERASE_BACKGROUND,function() end) --Neither of them
are needed in earlier wxLua anyway.
end
function OnSize(E)
CX,CY=FRAME:GetClientSizeWH() PANEL:SetClientSize(CX,CY)
LAYER:SetClientSize(CX,CY) CX,CY=CX-BX,CY-BY
if OX<CX then OX=CX end if OY<CY then OY=CY end LAYER:Refresh()
PANEL:Refresh()
end
function OnMotion(E)
if E:LeftIsDown() then
OX,OY=PX+E:GetX(),PY+E:GetY()
if OX>0 then OX=0 end if OY>0 then OY=0 end if OX<CX then OX=CX end
if OY<CY then OY=CY end
CHART:Move(OX,OY) LAYER:Refresh()
end
end
Main()
