Hi Christian,
if you try this project:
main.lua
version (0.27)
title "test-mouse"
startnode (1)
1.lua
panel { "image.png",....}
posx,posy=pipmak.mouseloc()
pipmak.print(posx," ",posy)
Pipmak crash with access violation (this not happen with pipmak.clickloc() )
I'm investigated a little:
The access violation is caused by member-method thisCNode->mouseXYtoHV
which it isn't initialized as all of the methods of CNode
at time of calling mouselocLua()!
pipmakLuaLib.c:
static int mouselocLua(lua_State *L)
thisCNode->mouseXYtoHV(thisCNode, mouseX, mouseY, &h, &v);
This is the calling sequence which cause te error:
nodes.c:
CNode *loadNode(int nodeID)
.....
.....
/* at this point mouseXYtoHV isn't initialized */
call pipmak_internal.loadnode from default.lua
....
default.lua: --now execution continue in lua
luaDofile("node.lua")
which call mouselocLua
which call mouseXYtoHV -->not defined: error!!!
.....
.....
/* now mouseXYtoHV is initialized but it too late!!!*/
case NODE_TYPE_PANEL:
makePanelCNode(thisCNode); //this initialize mouseXYtoHV !!!
.....
.....
I think it should be possible which the problem happen also with other
functions...
I think you have to move the initializing of methods of CNode before calling
pipmak_internal.loadnode
It's very interesting how you have implemented OOP in C, I never seen
before!
