keyboard focus to the control of the chain

I have a sub - VI that is called automatically to the top in many situations in my main VI.  Essentially, the user could use the mouse to interact with him, but I also want the user to have the ability to use the keyboard.  There are control only one string (called display) that the user can type in, and everything I want to do is for the 'focus' on her keyboard so that the user can type into it without first having to click on it.  Is this possible and if so, how?  I tried and so far failed.

I also have another question about the attached VI.   You'll notice that I use two local variables for the above chain control.  I tried to eliminate the possible race conditions, but always wonder if there is a medium or even necessary to get rid of them.  Please notify.

Thank you in advance.

  • for debugger, shortcut moves keyboard focus to the component source from research

    I'm in the debugger and use the search function to find a definition of the function by pressing ctrl + d. I select the function definition.
    It works great so far, but the focus of the cursor is always in the search window. In general, I now want to set the focus on the source pane (so I can scroll, set breakpoints, etc.). However, I can't find a shortcut to the source window. Y at - it a shortcut or other quick way without using the mouse?

    Thank you

    I couldn't find a shortcut or the other, then maybe suggest to add such a feature.

  • Losing keyboard focus when the remote desktop session

    Hello

    I have several computers Win7 it remote to the server of a hosting company. Our users will register in the servers of the hosting via remote desktop. The question that arises is that the keyboard stops working after a locking of the user, the computer, then returns after a short period of time to continue working. The remote desktop session will remain functional when the computer is locked. After unlocking the computer, the keyboard does not work in the remote session. The mouse is not affected by this and minimizing the session, the keyboard works fine on the local session. Sometimes, you need to restore down and then restore back or minimize the RDP session several times to get the keyboard works within the remote session. A few times, close the RDP session will cause the keyboard work again. Someone at - he lived it and have a resolution of this problem? This issue seems to occur more frequently and we have already created on the remote server user profiles, but nothing helped. Thank you for your help.

    Hi Jon,
     

    Thanks for posting your question in the Microsoft Community Forums.

     
    The question you posted would be better suited for COMPUTING public Pro on TechNet. I would recommend posting your query in the TechNet Forums to get help:
  • Keyboard Focus & using the Tilde key

    My style of editing frequently involves using the hotkeys (SHIFT 1, 2, 3) to change the interface panels.  However, I've found that the development of offset and following this with the help of the tilde key to maximize the selected pane do not work.  The previously selected Panel always maximizes instead of the just-selected Panel.

    I'm doing something wrong or is - necessary to click with the mouse on the Panel wanted to ensure that, then using the tilde actually maximizes the Panel I want to maximize?

    I use CC PP on a Mac.

    The tilde key maximizes the sign that hangs over the mouse.

    Using Shift-~ maximizes the selected Panel.

    You can change this if you wish in the shortcuts menu.

  • menu bar popup not working if the focus is on the control of the chain

    Dear all,

    I wonder if this is the behavior expected or if I'm doing something wrong:

    On a Panel, I have a control of the chain; on double click, I opened a file selection box to select a file, then the file name on this control of the chain. After this action, this string is the active control, indicated by the gray frame.

    I also have a menu with some defined keyboard shortcuts bar for example F2. It seems that F2 is not functional, long as the focus is on the control of the chain. It's embarrassing because the typical user action is selects a file and then pressing on Fx. To resolve this problem, the user should click somewhere on the Panel to move the focus to another control. Of course this could be done programmatically, but the extra effort is not to say necessary for controls ring or digital controls. Also in digital controls, I can change the numbers, but even if a digital control is the active control due to the edition of the F2 value works immediately.

    Help is appreciated.

    Thank you

    I think what is happening here is that left double click is also used to highlight the text. So when you trigger the EVENT_LEFT_DOUBLE_CLICK, you're placing the text in the control of the chain and then also accentuating. It seems to be behaving strangely when the two of them occurs at the same time because of the order of the events. You can see that the mouse around when, returning from the file select popup causes the region highlighting to drag over the text. In this highlight mode, you cannot use the shortcuts for the menu. I was able to solve this problem by swallowing the EVENT_LEFT_DOUBLE_CLICK after you set the value of the control.

  • Can I programmatically select a control in the chain?

    I'm trying to programmatically select a control of the chain on the front panel for use with a scanner. The scanner will scan a bar code, and then write the data. It basically as a keyboard. Is it possible to programmatically select a control of the chain without going through the user click the control on the front panel?

    Just use a key Focus property node. Right click, create > property Node > Focus button. Change to write and connect a true him.

  • Using a control of the chain with the Enter key, return * and * allowing repeated identical entry

    Hi all

    There must be a simple solution for this, but it's Friday afternoon, and my brain is not cooperating.

    I create a simple terminal through which a user can interact with an instrument. My question is about the only query string control. The button send and the Terminal Table are here for reference.

    Here is my desired behavior:

    (a) the user types a command in the field of the query, tape input or return. An event is triggered, and the request is sent to the instrument. The focus remains on the field in the query.

    (b) with any other action the interface user, the user types Enter or return again and again, by triggering an event that sends the request to the instrument every time Enter or return is typed. The focus remains on the field in the query.

    Here's what I have:

    This allows for one), but fails to b). The reason is, because the value of the field in the query has not changed, change value event does not fire when the user starts to spam keys enter or return. There is a way around this, as suggested by this post. Here is the solution in a few words:

    Instead of looking for the change in the value of the query command, the event fires for each key event to the bottom of the control and resembles a pressure of enter key or return. What attracts the user action, even if the content of the field of the request have not changed. The problem with this approach is that, when this event fires, I need to read the value of the query string order and send it to the instrument, but the value I get via the local Variable query is the old value, probably because the key down event fires before the value of query is saved as changed. Is there a way to programatically "enter" the contents of the control channel so it is recorded as a change in value, until I have the question via a local Variable? Is there a different way I should go about it? I'd rather not do anything that bound the input keys or return to this particular area, since I have many other UI elements that need these keys in my program.

    If not, is there a way to make the control of the fire 'Change of value' query string event when the user presses enter or return even if the value has not changed?

    Thank you for your comments!

    I thought about it.

    (1) control of the string (query) a value of update while typing.

    (2) save the key event down to the control of the chain. If the entry or return was pressed, send the state machine to the State 'send request '.

    (3) in the application 'send' State read control channel via the local Variable value.

    This is the desired behavior to allow the user repeatedly hit entry or return to regularly send a command, and the user can also type in a new order and send it by pressing enter or return.

    Thanks to all who have helped me this something to think about!

  • Give the screen keyboard focus

    Hello

    I'm developing an application for a touch screen computer. Under windows, when you have a touch screen text area when given focus happened upward with a small icon to bring up the on-screen keyboard.

    I would like that to happen in our java application. I don't think that there is a feature like this built in and I think I could imitate if I could just give one-screen-keyboard focus of Java Windows. Does anyone know how to give a focus to window not java?

    I thought that it would be possible to do it from a batch file that java could then run or something if I can't do it from java directly.

    Thanks for any help

    Joe

    Suggestion: what happens if you create your own virtual keyboard using Java? Shouldn't be too hard, and then you have a pure solution of Java cross-platform, instead of having to resort to hacks like running batch scripts.

    Alternatively, you can look into the creation of a native DLL that can do what you want and then call by JNA. You essentially have a simple API to send windows messages, because it is the way you control the keyboard. This page can help you, it contains same sample Java code:

  • How to make the difference between the mouse down events in the control of the chain (click on contour vs click Center)?

    Hello

    I have a control over the chain on my UI and I would like to make the difference between mouse different events, that is to say, to be able to differentiate a click on the outline or the label of the controller vs right-clicking on the Center (between the control in "edit" mode)

    The reason is that sometimes if the user does click not in the Center but in the scope of control, Labview fires the mouse event down but the typed keys are not registered...

    Is it possible to distinguish the two?

    Thanks a lot for your help

    Set the string "update as you type" and use instead a "changed value" event Now, the event fires whenever a new character is entered.

  • Keyboard shortcut "Move the focus to the next window in the active application" system ignored

    Hello. Other than, for example, InDesign, Photoshop (12.0.2 x 64, Mac OS X 10.6.6 MacPro 4,1) seems to ignore the keyboard shortcut 'Move focus to the next window in the application active' systemic (in my case, and I think that generally, cmd - <). The key combination is not used by the set of keyboard shortcuts in Photoshop; in fact, Photoshop refuses to accept it as a shortcut, favourable to its use as a shortcut to System. But then why is inoperative in Photoshop and how to make it work?

    Thank you very much

    Adobe uses Ctrl Tab.

    CTRL F6 is the command of apple, I think you're talking about.

  • Set the focus to the text box of the embedded NumericStepper control

    I have an application that requires I use NumericStepper edit control as ItemEditor of a DataGrid column.

    I have two problems that I can't seem to overcome, one being the result of the solution to another:

    (1) I need to instantiate the component NumericStepper during execution, because I don't ' know advance what columns it will require.  More important still, I need to specify default attributes (styles, min, max, width, etc.).  I can't understand how to specify these attributes other than in a .mxml file.  To handle this, I have crreated a component 'wrapper' that's an HBox with a NumericStepper inside her, and I can specify my attributes on the tag NumericStepper.

    (2) now that I did #1 above, although, when I click a DataGrid cell that uses this component editing, the editor comes back but the text box is NOT centered, which means that the user must click a second time if he wants to type a number.  It's very irritating, but I do not know how to manage the focus such as when my HBox-with-embedded-NumericStepper' control rises, it concentrates and its selected data, NumericStepper, just as the 'base' is.

    So, my questions are:

    (1) can I somehow assign property values to a standard when executing NumericStepper, so that I can avoid using my built-in custom control HBox?

    (2) how can I manage the focus so that when my control HBox is in place, the text box is selected and fucused?

    That sounds confusing, but I have a small program to demonstrate this.  The "QtyBad" column uses my own NumericStepper HBos-based and not to be put in the correct focus when activated.  The "QtyGood" column has demonstrated APPROPRIATE behavior, as exposed by the native NumericStepper component, but I can't specify additional attributes / s on this subject.

    Here are all of the program - called "DGNumStepperDemo" - here:

    Any help is appreciated!

    Quick response to the #2 is to change the EditorDGNumericStepper.mxml to the following:

    
    http://www.adobe.com/2006/mxml"
               verticalAlign="middle" paddingRight="4" paddingLeft="4"
               verticalScrollPolicy="off" horizontalScrollPolicy="off"
               creationComplete="focusManager.setFocus(itemQuantity)">
         
              
         
         
    
    

    The only thing I did was put the NumericStepper to 100% width so it fills the column like the standard NumericStepper and it looks a bit better and I added a creation complete event handler that sets the focus to the NumericStepper.  I tested it and it will be emphasis each time on it like a standard stepper.  There may be a more "preferred" way, but it's simple and effective.

    On the #1 question, you want to change the properties, styles, etc. of a NumericStepper standard once it has been added to the data grid?

  • Setting Focus on the starting control

    If I have a line:
    txtUserID.setFocus ();
    in the function called by creationcomplete, control gets the KIND OF focus. I see the outline around the control, but I can NOT TAPER. I have to click the control with the mouse, then it works. Once the program is running, then any call to setFocus() works very well. Any suggestion please?

    It is a problem of knowm in which the reader Flash itself doesn't have the focus in the browser.

    Workarounds involve javascript in the html wrapper that sets the focus to the Flash Player object on pageLoad. Twelve, setFocus will work as expected.
