In Keyboard Extension, in UIInputViewController, I can get notified through textDidChange(textInput: UITextInput) of any change, and use self.textDocumentProxy.documentContextBefore/AfterInput to get current text.
Problem arise when user 'select text'. The 'before' and 'after' "sees" only the part before and after selection.
Is there any way to know if user touched any of the Copy-Cut-Select in a textField (given - we don't have access to that field from Keyboard Extension)?
Something like:
if(self.textDocumentProxy.someProperty == UIDocumentProxyTextCut)
Or any other way to know which of the UITextField action (Copy/Cut/Select) did the user took?
I think we can not find out if user touched on Copy/Cut/Paste menu
Because a custom keyboard can draw only within the primary view of its
UIInputViewController object, it cannot select text. Text selection is
under the control of the app that is using the keyboard. If that app
provides an editing menu interface (such as for Cut, Copy, and Paste),
the keyboard has no access to it. A custom keyboard cannot offer
inline autocorrection controls near the insertion point.

P/s:
I saw self.textDocumentProxy.documentContextAfterInput is always NIL. Who know why?
How can we know where the cursor is to provide suggestion for user?

The NSTableView has a feature, called Type Selection, by which the user can type the first letters of a listed item and the view automatically selects the first hit and scrolls to it.
I like to have a similar functionality in a NSCollectionView, where I list images by name.
Before I start writing such code by myself, I wonder if there is an API that can help me with this.
I am especially worred about getting the timing right, as I want to have it use the same timing as the NSTableView does. I imagine that it even changes depending on the user's System Preferences for typing. Also, the NSTableView will select other items with the same typed prefix if waiting long enough. All this can get quite complicated if I want to get it right. I don't want to miss anything.
First of all hi guys!
I was trying to write a mouse controller app for mac os x which is reading inputs from keyboard and moves the mouse accordingly. By garbage input i will describe the input was intented for a mouse event but it creates text on screen.
Before anyone points to the fact that there is a built in one, It was laggy even in shortest lag setting and cannot registers more than two buttons at the same time (you have to press diagonals to go to the diagonal.) If you accidentally press another button when release of the accident button your motion stops. My first and last reaction was "rubbish!". Adding customization and extra features is my goal.
I want to create a key combination that will block the garbage input to be passed to other programs while it was held. But global monitoring and seems like it always passes the event. And unfortunately I see qqqqqqqwwwwwww like text in unwanted places.
I want to see that when i press q w and up, it will make the mouse go up. But i create qqqqqqqwwwwww mess on the way. My first idea was creating a view on popover and handle events there, but whenever I want to use my mouse from keyboard seeing a popover is anoying and I couldn't find a way to show the popover without leaving any garbage keyboard input.
What should i do in this situation?
You will want to use Quartz Event Taps. Note that for an application to tap keyboard events, it has to be trusted for accessibility (as in System Preferences > Security & Privacy > Privacy > Accessibility). Your app can ask to be made trusted using AXIsProcessTrustedWithOptions().
I'm working on a applescript to update the content of a document in Microsoft Word. The updating process is quite long (might take more than 5s). So I want to prevent users to change anything during the updating. Do you know whether Microsoft or Applescript a function like that?
In Windows, I can just display a User Form (which is a dialog telling that "we are updating... ") and close that form when it's done. However, I don't know whether I can do the same in Mac (with Applescript alone).
When you say "applescript", I don't know if you mean "plain" applescript or the AppleScriptObjC version. If you mean the latter, then I know ways to do it.
One way I've used during slow processes is to put an overlay view over the whole content view of the window. I make it translucent white to partially obscure the window, and put some kind of message (and maybe a progress indicator) on it. You can just use an NSBox (of the custom type) in IB to make this, and then make a subclass of NSBox to color the view and override mouseDown:. MouseDown:, doesn't need to have any code in it, just by overriding it, you capture any key and mouse events so they don't accumulate on the event queue, and get used by the view below after your overlay goes away. Here's code I've used:
script Overlay
property parent : class "NSBox"
on awakeFromNib()
set overlayColor to current application's NSColor's colorWithCalibratedWhite_alpha_(1,.8)
setFillColor_(overlayColor)
end
on mouseDown_(theEvent)
--log "mouseDown"
end
end script
I have this view as the top most view in the view hierarchy, and set its hidden property to true until I want to show it.
I've got some code that grabs the TaskBar buttons and their text from the windows TaskBar using User32.SendMessage with the TB_GETBUTTON message to retrieve a TBBUTTON structure (Win32 API via C# P/Invokes). But I'm trying to figure out how to then, once I have the handle to the button, grab the associated context menu text. There is some status information on there for a specific application that I would like to retrieve. The button text gets me some of it, but I need to the context menu text to complete it.
Any ideas?
This is not completely clear... Context menus don't have text, as such - they have menu items, each one of which will have text. By "context menu text", do you mean the text of the menu items in the taskbar button's popup/context menu? For example, "Restore", "Minimize" etc in the screenshot below?
If so, I suspect you're going about this the wrong way:
This menu doesn't belong to the button, but is the system menu of the window represented by the taskbar button. If the button has a context menu, this is probably for a grouped collection of windows, not one specific window (or even windows for one process.)
Making judgements based on the context menu of a window sounds like a dodgy approach to me, especially based on text since that will change depending on where in the world your user is located. Applications can also change the contents of this menu so there's no guarantee it will contain something you expect to be there. It would be better to check the window style, if it's minimized, etc, to find out the information that also affects the contents of the menu.
I'm going to answer this based on what your needs seem to be from the question, not what you've directly asked, since (a) it's not possible as asked and (b) I think you're trying to do something else. (As a general guideline, in a question it's good to state why you're trying to do something - and even maybe ask about that, ie 'how do I achieve X' - in case there's a better method than the one you're using. Here, X is probably 'find out information about this window' not 'get the text of the context menu', because that's probably only one possible method to get to X.) Also I think extracting data from the internals of a third-party application like Explorer (the taskbar is an Explorer window) is fragile and prone to break in future versions of Windows.
The system menu or window information (whichever one) belongs to application windows. Unless taskbar buttons are grouped (and then it's the subitems) one taskbar button corresponds to one specific window in the system. So what you want to do is find these windows. You do this by:
Using the EnumWindows function
Then for each window that is passed to the callback, checking the extended window style using GetWindowLong with GWL_EXSTYLE to see if the WS_EX_APPWINDOW bit is set
In addition, sometimes other windows are shown: these heuristics should help.
Each one of these windows is a window that should appear on the taskbar, Alt-Tab dialog, etc.
You say you're getting the text of the taskbar button - this is probably the window caption of the window, and GetWindowText is the canonical (read: probably a lot more reliable) way to get the caption of a window belonging to another process.
If you really want the popup menu, then:
Use GetSystemMenu to retrieve the handle for the system menu for the window. Applications can customise this, so if your app is doing this (and that's why you want the popup menu) ensure you pass false to the bRevert parameter
You can then get the number of menu items using GetMenuItemCount and for each one call GetMenuItemInfo to get info about each menu item. Pass true to the fByPosition parameter to indicate you're accessing the menus by position (since you know the count, you're getting item 0, 1, 2... count-1).
This fills a MENUITEMINFO structure, which (I think, I haven't ever had to code this so I haven't tested) will tell you the text associated with an item via the dwTypeData field "if the MIIM_STRING flag is set in the fMask member".
If you really want information about the window status, you can get this information using methods like IsIconic to see if it's minimized, GetWindowLong again to get other information, etc. I'd suggest you ask another SO question about how to get whatever specific information about a window for details.
Hope that helps!
I want to get the currently selected item (text, image, etc) and display in my Cocoa app's window when a keyboard shortcut is hit. Droplr has functionality like this, for example. How do I go about doing this?
For example, I want it to return "(text, image, etc)" as text when that text selected on the screen like this: http://drp.ly/JAdv
The easiest way is to write a service and assign a keyboard shortcut to it. Services are designed to do exactly this: operate on the selected text, graphics, etc. (or insert information at the selection).
NSResponder * activeControl = [currentWindow firstResponder];
