    - by djerry
    Hey guys, I'm trying to sho a contextmenu on right-click on an item in a listbox. So i'm binding a list of "Users" to my listbox. Then i'm a bit lost. I thought i could foreach the list and add a mouserightdown event on the listboxitems, but i can't figure out how. Is this a good way, or does anyone know a better way of accomplishing what i want. Thanks in advance.

  • Creating a KeyDown Event Handler for the Label Control

    - by j-t-s
    Hi All I'm sure you're all aware of the fact that the Label Control has no KeyDown handler (and why would it?)... Anyway, I'm in need of a KeyDown handler for the Label Control and would appreciate any pointers/suggestions to get me started. I've searched around but haven't found any info on creating my own Event Handlers for the Label Control. Can this be done is C#? Thanks

  • why PaintComponent event in Java happen everytime I use its Graphics Event?

    - by Pooya
    Consider this code: public class StateChartPanel extends JPanel { private LightContext LC; public StateChartPanel(LightContext lc){ LC=lc; } public void paintComponent( Graphics G ){ super.paintComponent( G ); LC.DrawStateChart((Graphics2D)G); } } StateChartPanel is a panel to draw something (a state chart). It sends its Graphics object to LC which use it to draw shapes but whenever it draws something the PaintComponent event of StateChartPanel happens again and it causes my application to hang.

  • Keyboard- and mouse-event transparent widget

    - by Gajender
    When i click a button my main window i want it to become transparent to keyboard and mouse events, i.e. all keyboard and mouse events should pass to any windows below it as if that window is not present there. "Qt::WA_TransparentForMouseEvents" does not work here as this only make child windows transparent to keyboard and mouse events i guess. And my window is main window and i want to pass all event to any window on desktop not just parent window.

  • Hook a javascript event to page load

    - by Jagd
    I have an aspx that has the following javascript function being ran during the onload event of the body. <body onload="startClock();"> However, I'm setting the aspx up to use a master page, so the body tag doesn't exist in the aspx anymore. How do I go about registering the startClock function to run when the page is hit and still have it use a masterpage?

  • event handling in C++

    - by Max
    Hi. I'm writing a game in C++, and I'm trying to get it to recognize keyboard and mouse events. Google tells me that boost.signal is suitable for event handling, but none of the code samples or tutorials I've found tell me how to associate a keypress or mouseclick with a function. Can anyone shed any light on this?

  • Validating event usurps button click on Windows Form

    - by triskelion
    I have a ComboBox and a Save button on my Windows Form. When I change the selected value in the ComboBox then click the Save button, the ComboBox validating event fires but the button click is lost. When the selected value is valid this results in the user thinking they have saved the change when in fact they have not. Why is the button click lost if the ComboBox is valid? Is there a work around?

  • Bind an event handler to multiple elements jQuery?

    - by Alex
    Hello all. I've done some experimenting, but can't seem to successfully bind one event handler to multiple elements using jQuery. Here's what I've tried: $('selector1', 'selector2').bind('click', function() { $('someSelector').removeClass('coolClass'); }); I've tested all my selectors, and they are all valid. Is what I'm trying to do even possible? If so, can I do it with .live() as well? Thanks!

  • Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

    - by Madiyaan Damha
    I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running the default Ubuntu VNC server. I have another computer that has a resolution of about 1200x1024 that I use to VNC into the server using the default Ubuntu VNC viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how Windows Media Player or VLC scales down the window (and does some interpolation of pixels). Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there.

  • Printing on Windows 8 with PDF viewer (Adobe Reader) from network

    - by Bongo
    i have a problem with the Adobe Reader 8, but the problem seems to be equally bad with other pdf viewers. Here is the configuration: My PDF viewer is located on network drive "Z:" which is the network adress \dgs-main\progs. I tried to start the adobe reader from here - \\dgs-main\progs\Adobe\Reader 8.0\Reader\AcroRd32.exe and open the PDF from here - C:\Users\ServiceDesk\AppData\Local\Temp\GeneratedPDF.pdf The problem is as follows, if i open the PDF with a local PDF viewer everything works fine and i can print the document. If i open the PDF with the Network PDF viewer then it opens, but printing is impossible. The error message states: "Unable to start print job. Is printer available?" As mentioned above, it works with a local pdf viewer. In both cases i use the same printer. The Printer is a network printer but even with a local printer it fails. The error occurs only on Windows 8 machines. On windows 7 it works fine. I Hope somebody can tell me what the problem is. Thanks in advance and have a fine day.

  • An XEvent a Day (31 of 31) – Event Session DDL Events

    - by Jonathan Kehayias
    To close out this month’s series on Extended Events we’ll look at the DDL Events for the Event Session DDL operations, and how those can be used to track changes to Event Sessions and determine all of the possible outputs that could exist from an Extended Event Session.  One of my least favorite quirks about Extended Events is that there is no way to determine the Events and Actions that may exist inside a Target, except to parse all of the the captured data.  Information about the Event...(read more)
