Buttons in the ListView not pulling onAction

I have an application that worked with JavaFX JDK 7 2 but seems to no longer work in JavaFX JDK 8 8.  The story is that I have a ListView where I put my own CellFactory.  Within the class that extends ListCell in updateItem() method, I create a HBox containing text and a new button.  I write a reminder of onAction() for the button.  The final result should be a list with entries that contain buttons and when a button is clicked, the onAction() callback is called.  However, when I run it and click on the button, the callback is NOT triggered.  This exact code worked on JavaFX 2 and JDK 7.  Does anyone know of known issues in this area?

This issue has been seen before. See for example JavaFX 8 buttons in ListView

(There's a discussion somewhere else, but I can't find right now).

in the updateItem() method, I create a HBox containing text and a new button.

This is probably not a good approach anyway. You should really just create the HBox and the button once for the cell and in the updateItem (...) method make the button according to your needs. The answer in the link above uses this technique, which is both more efficient and provide a workaround for the bug.

  • button in the datagrid not pulling cell click event

    I have a datagrid with a custom button built in Actionscript rendering engine. I'm trying to figure out how to capture the click event of the component when the button is clicked.

    I am generating the component of the cell based on the field type:
    column.itemRenderer = new ClassFactory (DpFileRenderer);

    The element itself:

    package joe.ui {}
    Import mx.controls.Button;
    import flash.events.MouseEvent;
    import flash.events.Event;

    SerializableAttribute public class DpFileRenderer extends button
    {
    [Embed("/assets/icons/drive_disk.png")]
    private var diskIcon: Class;
    [Embed("/assets/icons/drive_disk_grey.png")]
    private var diskIconDisabled: Class;

    override the updateDisplayList(unscaledWidth:Number,_unscaledHeight:Number):void function
    {
    super.updateDisplayList (unscaledWidth, unscaledHeight);
    This.label = this.listData.label;
    If (this.listData.label! = '0')
    {
    this.setStyle ("icon", diskIcon);
    } else {}
    this.setStyle ("icon", diskIconDisabled);
    This.Enabled = false;
    }
    this.labelPlacement = 'left ';
    this.setStyle ("color", 0x000000);
    }
    }
    }

    I don't know exactly on where to put a diffuse in this event.

    Could someone help?

    Thank you.

    Add an event listener in the constructor of your rendering engine and dispatches the event from the Manager. You certainly want the event to bubble as well.

    Here's an example, using a text control, but the theory is the same.

  • Send the Contact not crisp Simple button text

    Hello world

    Why is it not the text on my button send the touch not crispy compared to other fonts of the form? I almost tried everything. but it still looks like his record as an image. no idea how to solve this problem? Thank you very much!

    It is an old "number". The Muse team decided to use an image for the button 'Submit', because this guarantees the highest browser compatibility: submit button is blurred after the validation / preview

  • Is it possible to assign the hand tool in Photoshop CS 6-button of the mouse/pen?

    Hello Forums out there,

    So many questions Monoprice to address here. Before receiving this tablet monoprice for my birthday, I used to use an old bamboo Wacom Bamboo Fun Touch CTH - 661. Pen of the only tablets, I used to be able to use the low pen button to select brush and pen switch high panoramic of the image, I was working on that.

    I get that... and now all I can do is can assign mouse buttons to the buttons of the pen, not the keyboard shortcuts. Now I can only use the low pen button (select brush) because the right click which makes appear. Not so much for the panning of the image.

    IMPORTANT!

    I have already contacted Support Customer Monoprice and dead. Please DO NOT suggest to return to them with this problem

    I ask people, is there any possible way to fix this?

    Thanks for your time and any help you can offer

    But the fact remains that this isn't a Photoshop problem and we cannot help you.  I tried to find links that might be useful, because we cannot be of direct assistance for you.  I've based my theory about them being new by the fact that I had never seen a reference to the Monoprice products after years of helping people on this forum and didn't know they still existed, but in recent weeks, we suddenly had a number of questions about them.

    My last disposable link was intended to clarify the situation and not a serious attempt to help.  The previous suggestions "were" a serious attempt to help, and it took several minutes looking for your problem for you.

    What particular Tablet do you have?  There keys Express, you can use instead of the bottom mouse button?  I own an Intus4 and 2 Companion Cintiq and find the keys to the invaluable Express.  With the Cintiq complementary 2 I use a small keyboard to the left and I have experimented with the use of a ShuttlePRO2 of outline drawings (I used usually only with Premiere Pro and After Effects) but it increases the usability of the Cintiq.

    If Monoprice pilots are flakey, and it seems that they are, then all I can say is you are trying to find workarounds until, if ever, they fix their drivers.

    Good luck.

  • With the help of a button in a ListView

    I have a button in one of my ListItemComponents.

    This button "consumes" the click event and emits clicked, but:

    of the ListItemComponent I can not access the external qml page (or classes registered c ++).

    When I click on another part of the component is called the ListView onTriggered, but not when I click on the button.

    Is there a way of

    -disable the "use-click" behavior of the button or

    -access the class qml or c ++ from the ListItemComponent

    ?

    Now I could have totally misunderstood the question, but that's what I thought you were asking... The same would go for if you used a custom component qml as the content of the listitemcomponent. You would access listview, like inside this category, or a gesturehandler defined inline in the definition of listitemcomponent.

    Container {
        id: page1 //or whatever component with a context property set for your c++ class
        ListView {
            id: mylistview
            ListItemComponents: [
                ListItemComponent {
                    id: mycomp
                    Container {
                        id: containerContents
                        Label { text: "my list item" + ListItemData.title; }
                        gestureHandlers: [
                            TapHandler {
                                onTapped: containerContents.ListItem.view.doSomethingWithItem(ListItemData);
                            }
                        ]
                    }
                }

  • C6180: To avoid damage, use the power button / shutdown - message does not disappear and the printer is looping

    I have problems with my printer since arriving to a new home. I stop the printer before removing the cable, but seems could have pulled the power cable earlier than closing down.

    Since that time, the printer is looping with message "to avoid damage to use the off button /...» "- How do I stop and work again.

    Please help!

    Thank you.

    Heck!

    I was really hoping that would not be the issue.

    So, if I understand it, the question you receive looks like this;

    "It lights up and shows the HP logo and process bar animation for one minute, followed by the message:"abnormal termination. "  To avoid damage use on the button to turn off the printer.  Do not use a wall or the band switch to close.  Press OK.  Then he stops and leaves upward. »

     

    Try this:

    1. If the printer is still on, unplug all rigid and flexible cables at the back of the printer.

    2 unplug the power cord also from the wall...

    3. wait for two minutes.

    4 reconnect the power cord to a wall outlet first.

    5. hold the pound (#) and six 6 buttons.

    6. all by pressing the two buttons, reconnect the power cord to the back of the printer and at the end of two seconds, exit book and six buttons.

    7. turn on the printer if it goes out...

    Third times the charm, right? * fingers crossed *

  • Method Get JDev 10.1.3.3.0, not pulling on the second visit

    Hello

    I'm having a problem with the accessor get and setters of my grain of support not pulling on the second visit to the page. When I visit the page for the first time, it works very well and the calculations are complete but when I revisit the page it doesn't work. Any help would be great. I have setup a custom but phaselistener do not think that is the problem as I tried it on a test page with only field based on him and it works very well.

    Thank you.

    "Revisit" a page can mean many things. Are you you speak by using the back button on your browser, or by using the in-application links to access the page? In 10.1.3 ADF is not really compatible back-button navigation. I've seen full button back-support for 10.1.3 House, but it is not easy (basically, it's doing things fantasies with frames, makuing sure that back button always navigates actually a hidden frame and Javascript in this context which submits to having again the previous page request). It's one of these things "I hope 11g coming out soon.

    If you actually go back to the page by using the links on the page, it's a little more surpsising. It is certainly the getter which is not put to fire, and not, say, code in the constructor of the Get accessor is dependent on? If the latter, make sure your scope of bean; It must be set to 'request', or you will be reusing an old bean rather than make a new. Otherwise, I'm at a bit of a loss.

  • button refresh Foxfire did not work when clicked on for the past two weeks

    button refresh Foxfire did not work when clicked on for the past two weeks

    Hi, see controls customize Firefox, buttons and toolbarsand click on restore default settings.

    If this does not help, Try Firefox Safe Mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

  • Middle button of the mouse - dosen't work not at all.

    So my action more used in Firefox was using the middle mouse button to open a new tab on a link. Suddenly after a format on my PC, the middle button of the mouse now refuses to be recognized by Firefox; He cannot even hold to auto-scroll or anything. I would like to confirm that the button works on other programs and games without any problem. Using using ctrl/shift + click is not perfect, but what I do until now. I use the latest version, here is a list of the things I've tried:

    -Check all the related: config with the "middle" in the search field.

    -Make a new profile and reset Firefox many times

    -Disabled people / removing addons/extensions

    -Wiping and installed Firefox completely - tried with no addons

    -Options checked

    Up here no luck at all, even no tried a few other browsers such as aurora & chrome with the same question basically.

    I don't know if you have a whimsical mouse with his own custom driver software. If so, it would be interesting to try to update the drivers. Alternatively, Firefox sometimes works best when switch you to the standard Microsoft mouse driver instead.

  • I do not have a button of the Firebox above the window of firefox. have tried to reset as do not have the toolbars. I have a right-click in the toolbar area-no options?

    Tried to add a menu toolbar or a toolbar of bookmarks. No options appear only when I click right in the toolbar area - or not to hide the toolbars. It was suggested to reset firefox by lowering a window by clicking the firefox button in the upper left corner. I don't have such a button. I'm frustrated and going around in circles. Your video on toolbars does not run. Pretend he does, but does nothing. I'm a Firefox user for years without any problem. Browser Firefox has diverted and unable to solve the problem because access is really a challenge. Avast suggested browser cleaning & even though it disappeared temporarily he returned. So I uninstalled Firefox and spent my allegiance to Google Crome. Favorite browser Firefox, however then reinstalled - and here I am. At the present time - not a satisfied customer! I'm running firefox on a Windows 7 operating system. I would try reinstalling but have already imported by bookmarks in Crome - this could be a part of the problem? Shouldn't be, I think. Thanks for any help.

    You were probably in mode full screen, if you had the ability to hide the toolbars in the context menu.

    You should also have seen the choice of exit full screen in this context menu.

    As reported above, pressing the key F11 will also toggle / disable mode full screen.
