Mach4 General Discussion / wxLua and wxWidgets questions
« on: November 29, 2017, 06:11:03 PM »
Hello everyone,
I'm developing a Mach4 Wizzard and am having a problem with grid blocks, specifically wxGridCellCoordsArray's returned by wxWidgets. I believe it is a result of a bug in a wxLua wrapper for wxWidgets.
A couple questions:
The two calls to GetSelectionBlock... work fine as a subsequent call to GetCount on each returns the correct value.
The call to Item(1) should return the first block’s row/col pair, but no matter how I try I can’t get it to return good values. I had some erroneous values at one time, but it wasn’t crashing the editor.
I have no expectation that anybody must troubleshoot this, but if some curious soul would like a try at it, I have included the code. Just put it in a menu or button event, of course.
Thanks, David
I'm developing a Mach4 Wizzard and am having a problem with grid blocks, specifically wxGridCellCoordsArray's returned by wxWidgets. I believe it is a result of a bug in a wxLua wrapper for wxWidgets.
A couple questions:
- The mailing list activity on wxLua's site has slowed to a crawl. Is wxLua still in development?
- This one is a longshot... Has anybody tried processing multiple block-selections on a grid? See the attachment for an example. Sample code is attached as well - to show syntax highlighting.
- Finally, does anybody know how to recompile wxLua with wxWidgets 3.01? Or at least how easy or hard it might be? Mach4 obviously has it done. I am developing on another machine without Mach4 installed and am using the Windows install of wxLua to develop with. The latest version from their web-page is compiled with 2.8.12.
Code: [Select]
local wxGridCellCoordsArray BTL = (grid:GetSelectionBlockTopLeft())
local wxGridCellCoordsArray BBR = (grid:GetSelectionBlockBottomRight())
print("BTL=",BTL)
print("BTL Count="..BTL:GetCount(), "BBR Count="..BBR:GetCount()) --These print to an output window in wxLuaEdtor
grid.SetCellValue(grid,2,0,"Ct="..BTL:GetCount()) --print doesn't show in mcLua, so I put it on the grid.
--correctly displays the number of blocks selected in the grid
local wxGridCellCoords topleft = (BTL:Item(1)) --this line blows up mcLua and wxLuaEditor
row = topleft:GetRow()
col = topleft:GetCol()
print("topleft=", topleft)
print("Row="..row,"Col="..col)
