Htmleditor and keystroke and backspace

hi:
i got a problem and have been gnawed for weeks.
i am using textpane to implement a WYSIWYG html editor. i wanner do an action when the BACKSPACE key pressed, but the action should occure before the letter be delete from the screen or model .
how can i do it?

Hi,
you can use the editor's KeyMap and override the respective keystroke with your action as in     Keymap map = getKeymap();
    KeyStroke bs = KeyStroke.getKeyStroke(KeyEvent.VK_BACK_SPACE, 0);
    map.addActionForKeyStroke(bs, new MyCustomizedAction());If the original action (delete letter) is to be done after your customized action has been performed, you can create a customized action which accepts another action in its constructor. In this constructor you then pass the original action for backspace and call this action from your customized one.
See a working example of the above in class SHTMLEditorPane of open source application SimplyHTML at http://www.lightdev.com/dev/sh.htm

  • Recording keystrokes and mouse clicks?

    Greetings,
    I need to be able to make scripts/macros by recording keystrokes and mouse clicks with location.
    Is this possible with Automator?
    Does anyone know of a way program to do this?
    It seems so simple.
    Thanks

    Keyboard shortcuts were often missed.  For example, I tried this sequence many times. 
    0: (setup:  text editor is scrolled to first line and cursor is at the beginning of the first line)
    1: Click on text editor window to focus it.
    2: press SHIFT-DownArrow to move cursor down one line and select the first line
    3: press CMD-X to cut the line.
    Automator never would capture those key strokes. 
    But today I has a break through.  This sequence does work:
    0: (setup:  text editor is scrolled to bottom of the file and the cursor is placed below the last line.)
    1: Click on text editor window to focus it.
    2: press SHIFT-UpArror to move cursor up one line and select the last line.
    3: press CMD-X to cut the line.
    about 70% of the time this did get recorded correctly (I did maybe 3 recordings and one failed to select).  Once it got recorded correctly it worked reliably. 
    So it seems to be able to capture some sequences but not others.  Both sequences work very reliably when I type them but automator can only capture the last sequence. 
    Thanks for the suggestions.  This tool is better than nothing but not anything I would recommend.

  • Every keystroke and mouse movement, I get an audio notice that I need to shut off. In Safari, the cursor cycles thru every link and metadata field and I get a verbal/audio notice of what it is.  How do I shut this option off???

    Press the key combination command-F5 to deactivate VoiceOver. If that doesn't work, proceed as follows.
    For OS X 10.7: From the menu bar, select
     ▹ System Preferences ▹ Universal Access ▹ Seeing ▹ VoiceOver: Off
    For OS X 10.8 or later: Select
     ▹ System Preferences ▹ Accessibility ▹ VoiceOver ▹ Enable VoiceOver: Off

  • Can clips retain last playhead position and in and out points like v7?

    Is there a setting that will enable the clips to retain the last playhead position and in and out points so that I don't have to find the place I left off at every time I go to that Clip? Basically how FCP 7 worked.
    Vince

    This is another area that's lacking in this great application, I'm afraid - but there are ways to keep the 'in and out' points at least.
    When you have marked them you simply press 'F' to mark your selection as a favourite. Then if you click the green bar that appears, your selection will immediately be highlighted.
    Alternatively, add keywords to your selection - then when you click the keyword collection in the event browser, the clips will be displayed, already trimmed.
    A third way is to trim away the unwnated footage in your clip. Lets say you have a long clip and you want to make multiple clips from it. You don't want the first three seconds of the clip and you also don't want the last one second . . . (follow this carefully - it works)!
    Move the playhead to your IN point and press the 'O' key (yes the 'O' key).
    Now press the backspace key and your clip is trimmed to the 'in' point. Now scroll to the out point and press the 'I' key (that's right). Move the playhead to the 'in' point of your next clip and press 'O'.
    Press Backspace and your clip stands on its own for all time.
    (You can even mark one frame 'Out' and the very next frame 'In' and this will work - you don't lose any frames).
    Sorry I can't help you with retaining the playhead position.

  • I got a new macbook pro and am having a great deal of trouble with it from the start!  But other than that, which I will get to, I have had macs since the one following Lisa and I am a diehard apple fan, yet now with the macbook pro and Lion and its

    I could not download the upgrade to the mountain lion. my updates were taking an enormous amount of time for other programs. When I finally got the indication it was waiting to be downloaded I had to shut down. It was after 2 am and I was practically unconscious already with all the trauma of trying to find the right place for the redeem of the code to open the password. It was all confusing and poorly communicated by Apple. The terrible deterioration of Apple's written communications by non-American techies who can't write for easy understanding, even by this old time tech afficianado is heart-breaking and frustrating is putting the effects mildly.  I have not yet gone back to the mac book pro to finish the job. I am too frustrated and unhappy with the new system.  Also, I found out the hard way that my time capsule saved files on the macbook Snow Leopard, which still works fine after 6 years of use, is locked in that external drive and I cannot transfer the items except one by one or by folders on that computer to a DVD or to a flash drive, to mport to this new computer. Because the systems are not the same, I can't access the files automatically. I fear I will have further problems with the mountain lion vs. lion in seeing those files. What can I do? What should I do?  I am afraid to designate an external hard drive I purchased with the new laptop for the time capsule because then it won't work with any other computer.  I read of terrible incompatibility issues and crashes and things not working right once Mountain Lion was installed and now I am terrified they will happen to me. I just wanted the computer to be as easy to use as all the other macs I have and have had and now it is more like a horribly complicated and difficult Microsoft IBM compatible PC. I hate this. Perhaps Apple wanted to appeal to new Apple users and tried to make them comfortable while disregarding the comfort of loyal Apple users?  It's a sell-out. Meanwhile, I have to get senior tech people because the kids who try to answer my questions much of the time don't interpret what i am telling them and it takes a pro.  Perhaps the kids can answer what I should do in preferenced to scroll the screen, since the scroll indicators disappear and I can't see them and have to resort to using the arrows on the keyboard, which is not the way I like to work.    Please advise me about all of these things!

    Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
    This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

  • The screen on my ipod touch is stuck zoomed in. I turned it off and back and its still stuck zoomed in. I also tried to reset it and that didn't work either. Please help.

    The screen on my ipod touch is stuck zoomed in. I don't know how it happened I just looked down and it was like that. I have turned it off and back and even reset it but it still keeps zooming back in each time I turn it on. I can't unlock it because I can't see the numbers and it won't let me move around the screen. Please help.

    This is asked and answered often.  The foru search bar is on the right side of this page.

  • How can I select more than one bookmark at a time so that I can then open multiple bookmarks -- without the aggravation of going back to the list and selecting and opening each one.

    From my dozens of bookmarks, I often would like to open 5 or 6 of them at once -- perhaps a couple of weather reports, a couple of radio stations, a couple of other websites. But I see no way of doing this without laboriously finding a bookmark, selecting it, opening the website, then returning to the bookmarks, finding the second bookmark, selecting it, opening the website, and on and on. Surely there's a way for me to select multiple unrelated bookmarks and open them at the same time. Thanks much for your help. Don

    ''Actually there is a picture and better explanation in the corresponding History article''
    * ''http://kb.mozillazine.org/Viewing_the_browsing_history_-_Firefox ''
    Look where this picture is embedded in the article topic [http://kb.mozillazine.org/Viewing_the_browsing_history_-_Firefox#Selecting_history_items Selecting history items]
    * http://kb.mozillazine.org/images/Fx3_history_sidebar_selections2.png
    Selecting, viewing, and searching the sidebars and library lists is explained in both articles previously mentioned.
    Multiple selection is something built-in to a lot of applications and into all browsers, and yes you guessed correctly the favicon it the thing to the left of the bookmark and that is what is is called in all browsers. And if you look at selection you will find that it matches what you asked for, especially if you were to do a search from the search bar on the bookmark or history sidebar. But there is also no problem opening up a single bookmark or history item into a new tab, with either Ctrl+click or Ctrl+Shift+click in the area to the right of the favicon either.
    However I would suggest making a change to your configuration options so the the same keyboard shortcut is used from a link and from your bookmarks. See those keyboard shortcuts in the following along with the footnotes just below the table for them in

  • Hello, I've updated the iPhone I have got I have a problem I hope you respond to some of the applications no longer work, such as the safari and skype and many applications are no longer working with the ios7.0.4

    Hello, I've updated the iPhone I have got I have a problem I hope you respond to some of the applications no longer work, such as the safari and skype and many applications are no longer working with the ios7.0.4

    Standard troubleshooting...
    1. Try a Restart by pressing the sleep/lock button until you see the slider.  Slide to power off.  Restart by pressing the sleep/lock button until you see the Apple logo.
    2. Try a Reset by pressing the home and sleep buttons until you see the Apple logo. Takes about 5-15 secs of button holding and you won't lose any data or settings.
    3. Remove apps from Recently Used (multi-tasking) list...
    - From any Home Screen, double tap the home button to bring up the Recents List
    - Swipe up on the app preview card to remove it from the list
    - Press the home button when done.
    4. If still a problem restore with your backup.
    5. If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
    6. If still a problem, it's likely a hardware issue.

  • HT201272 If I already downloaded my songs then accidentally deleted them from my computer, how can I redownload them? Itunes store shows them as downloaded and unless I go through and try and repurchase each song individually, it wont let me redownload. h

    How ccan I redownload my music to the same computer. Downloaded, then deleted, now i tunes won't let me redownload, because I already downloaded. If I go through and try and repurchase the songs it will download them for me but I don't want to have to do that 250 times.

    You need to delete the broken entries first, then the tracks will show up with the iCloud download symbols in your purchased histroy and IIRC you can download them all in one go.
