qt - How can QWindow replace QGLWidget? -


qt docs since qt5 should use qopengl* classes instead of qgl*.

problem there no qglwidget replacement. figured out instead should use qwindow in conjunction qopenglcontext , call setsurfacetype( openglsurface );.

only problem qwindow can't have qwidget parent. how can embed qwindow aka. opengl drawing surface other widgets?

qt 5.1 in weird situation opengl , qwidget (and derived) wise. there's no qglwidget replacement yet other qgl classes have clear replacements.

if don't want use old qglwidget indeed have manufacture replacement qwindow. so, first set qwindow then, correctly said call setsurfacetype( openglsurface ); before call create(); on it. create new qopenglcontext , use makecurrent() function , pass qwindow. create qwidget qwindow using qwidget::createwindowcontainer(window);

but temporary hack, shouldn't have use unless want mix qtquick qwidget. can replace temporary hack actual replacement in 5.2.0 5.4.0 called qopenglwidget

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
