问题 I'm writing a bit of code for a Gedit plugin. I'm using Python and the interface (obviously) is GTK. So, the issue I'm having is quite simple: I have a search box (a gtk.Entry) and right below I have a results box (a gtk.TreeView). Right after you type something in the search box you are presented a bunch of results, and I would like the user to be able to press the Up/Down keys to select one, Enter to choose it, and be done. Thing is, I can't seem to find a way to forward the Up/Down

问题 My google-fu has failed me. I've got a pretty simple script that just tests ping connectivity from one server to another, and displays a runtime at the top. I'd like to be able to stop this script at any time with a single keypress ("q" in the script) and have it give some basic stats about how long it ran, and how many times it failed. I can stop the script with ctrl+c, but that completely exits and doesn't allow me to show any stats. Below is my script. Any help is appreciated! ############

问题 I use VC++(VS2008 Express) to develop a C++ console application.(well, not exactly: from the console,another window(provided by 3rd party library which does not provide any API to process keypress events on the image) opens which displays a camera stream. I am new to windows programming. I like to detect the keypress of the function key(lets say F1) and change some parameters of the camera like its brightness in real time, that is, when the F1 key is pressed, i d like to see the camera stream

问题 I need to get the text of the keys at the event of key press in Blackberry. This happens when the user presses a key from the the keypad in order to type text. How is that possible? 回答1: you can get the pressed key text by overriding keyChar like this public boolean keyChar(char key, int status, int time) { if (key == Characters.ESCAPE) { int result = Dialog.ask(Dialog.D_YES_NO,"Are you sure you want to exit?"); if (result == Dialog.YES) { closePopup(); } return(true); } else if (key ==

问题 I'm trying to read a MIDI file and then convert each note (midi number) to a simulated keypress on the keyboard (A,f,h,J,t...). I'm able to read any MIDI file with the python-midi library like this: pattern = midi.read_midifile("example.mid") and I can also simulate keypresses with pywin32 like this: shell = win32com.client.Dispatch("WScript.Shell") shell.SendKeys(key) But I have no idea on how to actually convert midi numbers (that are in midi files) to keypresses. To be more precise I'm

问题 I'm using this to disable the 'scrolling' effect the spacebar has in a browser. Will this affect other keypress events too? window.onkeydown = function(e) { return !(e.keyCode == 32); }; Could someone please explain what this is doing? I'm not sure if this code is bad, but it seems to disable other keypress related codes in my page, and I want to make sure this isn't the reason. Thanks! 回答1: ASCII code 32 is the ASCII value that represents the spacebar key, and your code is essentially

问题 I just recently began in C# development, and I was working on a forms-based project and I am trying to perform a "tab" action when the user is on a form and pressed the Enter key. I know the answer is probably quite simple, but I am a newbie in this realm. 回答1: Welcome to SO Tex, I believe there are two methods to accomplish this, would just involve adding: Option 1: Grabbing the Next Control if an Enter KeyPress was performed In the properties of your form, set the KeyPreview property of the

问题 Community, There is a way to prevent an active combobox from losing its focus when hitting the down arrow (or up arrow) when at the end (or start) of a list. If there is a better way to do this (preferably with an MS standard property) please share. Problem: When at the end of a list in a ComboBox, if you hit the down arrow it will move you to whatever control is physically below the active combobox. Vice versa for being at the top of a combobox and hitting the up arrow. This is sloppy and
