there difference in push constant value directly call function, instead of mov value eax , push eax. for example in c: getstdhandle(std_output_handle); many compilers generate this: ;b8 f5 ff ff ff mov eax,-11 ;50 push eax call getstdhandle and manually i'm using; ;6a f5 push -11 call getstdhandle there wrong pushing value directly instead load on eax , push eax ? what have should ok, assuming code in 32 bit mode. you explicitly specify 32 bit immediate, in case of visual studio (2005) assembler (ml.exe), used full 32 bit operand size instead of sign extended byte value: ; 68 f5 ff ff ff ; push dword ptr -11 even specifying byte ptr visual studio's assembler (ml.exe) works: ; 6a f5 ; push byte ptr -11 however, using word ptr results in 66 prefix , 16 bit push (esp subtracted 2 instead of 4): ; 66 68 f5 ff ; push word ptr -11 in case 66 prefix changes operand size (the value pushed onto stack) 16 bits. ...

after analyzing heap dump found there 30mb strings allocated (single string of 30 mb). there way set break point while debugging application can find code allocates these huge strings? since thousands of strings allocated during application run isn't possible putting break point on each string allocation. believe conditional break point slow well. if possible want exam strings content understand origin of these allocation. example may result of web service call called small amount of data in rare cases huge input (which cases want find). i'd try conditional breakpoint, if meant leaving app running day or two. @ least can on else while running. , other solution take day or 2 implement anyway. failing that, using aspectj add pointcut string constructors , use log message, throw exception etc. same conditional breakpoint should run more quickly.

this app draws graphic items flags itemismovable , itemisselectable. qgraphicsview handles keyboard , mouse interaction. i select smallest item in surface, if 2 boundingrects() collide; example, imagine 2 rectangles, 1 inside other. user clicking inside rectangle expect 1 selected. my ideas : (1) recalculate z-indexes each time item changes shape. seems little overkill. (2) reimplementing qgraphicsitem.shape() [ items segment paths - if selection on segments , not on bounding box, work ] - returning qpainterpath() didn't seem trick. (3) catch mouse events inside items first , (?) override default selection mechanism. seems overkill. is there easy way achieve goal? thanks, sébastien when user selects item , graphics view receives position, can use position, convert scene coordinates , call qgraphicsscene::items function. return items @ given position. now have list of items @ point user selected, can compare items find smallest , set selected .
