How to create a binding for NSApp.dockTile's

问题 In IB it is easy to bind a label or text field to some controller's keyPath. The NSDockTile (available via [[NSApp dockTile] setBadgeLabel:@"123"]) doesn't appear in IB, and I cannot figure out how to programmatically bind its "badgeLabel" property like you might bind a label/textfield/table column. Any ideas? 回答1: NSDockTile doesn't have any bindings, so your controller will have to update the dock tile manually. You could do this using KVO which would have the same effect as binding it.

问题 I would like to add Key bindings to my JFileChooser in order to open a file preview window when the SPACE key is pressed. Because of the source code is too big, I just did a simple dirty code : MainWindow.java package test; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class MainWindow extends JFrame { public MainWindow() { this.setTitle("Test Window"); Dimension dim = new Dimension(800, 600); this.setSize(dim); this.setPreferredSize(dim); MainPanel pane = new

Java Swing: Do something while the key is being pressed

由 ↘锁芯ラ 提交于 2019-12-07 10:56:01
问题 Im using a KeyAdpater to get the events and the method addKeyListener and works fine. The problem is that when a press the key, the action ocurrs only once and not while its being pressed, after 3-4 secs holding down the key the action occurs all the time which is what I want. I'd want to know if there is good way to do the action all the time the key is being pressed from the very begining , not after 3-4 seconds holding down. I thought on the next solution, but maybe there is already an

Java Swing: Show pressed button when using corresponding keyboard button

由 廉价感情. 提交于 2019-12-07 06:01:16
问题 I'm making a program in Java, using Swing, with a GUI that contains arrow keys. The arrow keys correspond to the arrow keys on the keyboard. When I press the up arrow key on the keyboard, I'd like the up arrow key on the GUI to show up as being pressed. Until I release the arrow key, it should show it is still being pressed, and when released it should also release. A snippet of my code so far (only for the Up button), which I think is totally wrong in the show being pressed category: ... if

Multiple-line cursor movements in XCode

由 南笙酒味 提交于 2019-12-06 12:20:05
I'd like to map a key to move the cursor in the XCode up by ten lines. Of course, I want another one to move down too. The key mapping would ideally be something like 'Control-Alt-P'. Is there a way to achieve this in XCode without resorting to Automator? Ashley has the answer below, the formatting was a little different as the property list is in XML format. In summary, added an entry in the following format to the 'text' section of *.pbxkeys in ~/Library/Application Support/Xcode/Key Bindings/: <key>^~p</key> <array> <string>moveUp:</string> <string>moveUp:</string> </array> Ashley Clark You

问题 Is it possible to define key bindings in WPF for a sequence of key presses like the shortcuts in Visual Studio e.g. Ctrl + R , Ctrl + A is run all tests in current solution As far as I can see I can only bind single key combinations like Ctrl + S using the element.

Something like that: public class MultiInputGesture :

Tkinter keybinding for Control-Shift-Tab

由 佐手、 提交于 2019-12-06 06:05:09
What's the key-binding for Control-Shift-Tab? I've tried lots of things and nothing seems to work. I'm already aware of tkinter.ttk.Notebook.enable_traversal. If you know of a handler for tabs being activated, that would suffice, too. Armin The general format for representing an event is: <[event modifier(s)-]...event type [-event detail]>. For key-binding Ctrl+Shift+Tab the format would be: 'Control-Shift-KeyPress-Tab'. In this case the event modifiers would be: Control- Shift-, the event type: Keypress, and the event detail: -Tab The following code (in python 2.7.6) should make it clear:
