I am having trouble integrating my own custom data type into Qt Creator,
although very simple:
struct int_image
{
int* pixels;
int tx; /* size in x-dimension */
int ty; /* size in y-dimension */
};
I defined a custom dumper like this (almost identical to
http://plohrmann.blogspot.de/2013/10/writing-debug-visualizers-for-gdb.html):
def qdump__int_image(d, value):
pixels = value["pixels"]
tx = value["tx"]
ty = value["ty"]
size = tx*ty
maxDisplayItems = 4000
type=gdb.lookup_type('int')
ptr=gdb.Value(pixels.cast(type.pointer()))
d.putValue('[%dx%d]'%(tx,ty))
d.putNumChild(3)
with Children(d):
d.putSubItem("tx", tx)
d.putSubItem("ty", ty)
with SubItem(d, "pixels"):
d.putItemCount(size)
d.putNumChild(size)
if 1:
#if d.isExpanded():
numDisplayItems = min(maxDisplayItems,
size)
with
Children(d,numChild=size,maxNumChild=numDisplayItems,childType=type,addrBase=ptr,addrStep=ptr.dereference().__sizeof__):
for i in range(0,numDisplayItems):
d.putSubItem(i,
ptr.dereference())
ptr += 1
file=open('/home/x/debug.txt','w')
file.write(str(string.join(d.output,"\n")))
file.close()
The output looks like this:
{
iname="local.grid",
name="grid",
addr="0x7fffffffde50",
numchild="3",
children=[
{
name="tx",
addr="0x7fffffffde58",
numchild="0",
type="int",
value="2",
},
{
name="ty",
addr="0x7fffffffde5c",
numchild="0",
type="int",
value="1953",
},
{
name="pixels",
numchild="3906",
childtype="int",
childnumchild="0",
addrbase="0x725ee0",
children=[
{
addr="0x725ee0",
value="0",
},
{
addr="0x725ee4",
value="0",
},
{
addr="0x725ee8",
value="2",
},
...
{
addr="0x729be4",
value="60",
},
],
value="<3906 items>",
},
],
But for "pixels" I only see <unavailable synchronous data> in Qt
Creator. I have already tried lots of stuff but the message stays the same.
Any idea what I am missing?
Best regards,
Eddy
