cocoa - What's the correct way to reopen a window on OSX? -


i've got app i've created in xcode. it's not document based.

how make when user clicks on say, dock icon, window reopens? i'm creating out nib xcode automagically gave me.

i've tried implement applicationshouldopenuntitledfile: , calling makekeyandvisible on app delegate's window property, messes app's icon. (i guess has icons serving document previews.)

regardless, i've googled bit, , found references carbon apis, or document based apps.

how window creation process work between nsapplicationmain , app's nib file, how can replicate process, , can so?

generally, find working nswindowcontrollers makes dealing windows much simpler. in case, app delegate wouldn't own window directly, instead own nswindowcontroller owns window.

to this, you'd create new nswindowcontroller subclass (with xib user interface), , migrate window mainmenu.xib new windowcontroller.xib. hook things up, , you're ready go. (also, make sure "visible @ launch" checkbox on window unchecked)

from app delegate, you'll create new instance of window controller (whether programmatically or via mainmenu.xib doesn't matter), , tell -showwindow: when want window show (or become key), , -close when want go away.

as responding clicking on dock icon, <nsapplicationdelegate> method you're looking -applicationshouldhandlereopen:hasvisiblewindows:.

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)...
