To remove a pointer in QML?

I have move some objects to my UI in c ++ using a signal. Once I processed them I want to clean them and remove them.

Can I do this in QML somehow, or should I send back a signal to c ++ to do it?

My current idea is to use the tree of QObject to have all subclasses with their pointers etc in the tree and remove only the pointer in the foreground, is this best practice or suggest something else?

As much as I know, there no way to delete items of QML C++ which were not created as types QML, and therefore you cannot pass a pointer to your components QML property.  Send a signal that calls the destructor is probably the next best thing.

Using tree QObject and defining carefully the parent on everything is the best way to manage the memory, but not the more granular, so it depends on the amount of memory you use.  In most cases it's fine work.

  • How can I remove restore points created daily by Software Distribution Service 3.0?

    Are not only all these points using the space on my hard drive to restore?

    A better program of disk cleanup is cCleaner. Delete System Restore points may be important if you have little free disk space. The ability to delete them is one of the tools options. You can selectively remove those created in less important moments.

    cCleaner also comes with a registry tool. Do not use this tool as any registry cleaner could lead to the creation of very difficult to resolve system errors.

  • How to selectively remove Restore Points in Windows 7 Pro

    The discussion that I found to this question did not address the selective deletion of restore points. It describes how to remove all but most recent which does not help me.

    Does anyone have an answer?

    Thank you!

    You are limited to the reduction of disk space used for the restore points. This will cause the oldest points should be deleted.

  • Remove symbol points or stop?

    Hello!

    I am currently doing the game design at the University and have recently begun to look 3 action script. I'm not too bad and can usually find the answer to what I'm looking for, but it only has really left me speechless. I want to add an element to a game that I do it so that when it is hit it gives a few points and disappears. We were taught to do this (so far) with hitTestObject and I'm having a problem where I can get the symbol of the element to disappear but I'm still in the position I still earn points. I tried to look for it, but I'm not finding something that works. So, any help would be greatly appreciated as I want to throw this laptop out the window right now

    This is what I have for my 'play' now, please excuse something crazy I'm just learning action script and have probably something crazy in there

    If the character key piece
    If (thief_mc.hitTestObject (coin_mc)) {}
    If (internship. Contains (coin_mc))
    removeChild (coin_mc);
    increase of 5 points
    score += 5;
    score_txt. Text = String (score);

    }

    Is it possible to stop at 5 points for the symbol or remove it to stop any other vantage point of being?

    Oh, you are missing a hug:

    If the character key piece
    If (thief_mc.hitTestObject (coin_mc)) {}
    {if (internship. Contains (coin_mc))}
    removeChild (coin_mc);

  • HOW TO DISABLE/REMOVE ALPS POINTING DEVICE IN W7

    How can I get rid of the Alps on the DM1, using W7 pointing device?

    If uninstall you from Device Manager, they will continue to return.  Effectively disabling the touchpad will make a decoration.  Most laptops have a sensitive button in the upper left of the touchpad.  If you doubltap this button, touchpad should become disabled.

    Some laptops offer this option in the properties of the mouse.

    1. go to start, search for mouse and open mouse in Control Panel.

    2. Select the device settings tab.

    3. the keyboard should be listed.  Highlight it and there should be a button turn off just below the text window.  By clicking on the button turn off should disable the touchpad.

    If I have the product number, I I would like to be able to check if it has the ability to turn off in the corner of the touchpad and provide more specific measures.  There are several models with the series DM1.

    Let me know what happens.

  • Is it possible to quickly straighten the lines or remove several points in a line

    Hi, sorry not too sure how Word of the question.

    I'm studying for a master of science in geology and do seismic mapping. For storing my cards I exported the ArcGIS for I can bring together various and also outline maps. Then I exported the GIS maps in illustrator so I could try some of the smooth contours because they are extremely jaggedy due to the nature of the data.

    Is there a way to quickly smooth lines or mass delete points that make up the lines?

    I ask because I have 30 + cards and each card has perhaps 50lines with each line consisting of currently about 1000 points each...

    If I can't find a solution I will probably end up drawing on the shape with the pen tool and smoothing just in this way, as it should be much faster, and then deleting as many points.

    Any help much appreciated.

    I am currently using Illustrator CS5 and have access to CS4.

    Thank you

    And if you're good with the rounded tool, the pencil icon drop-down, you might be able to use it to refine the contours as well.

    It that they are actually fished segments, then you can select paths and use the brand

    Adjustable rounded tool your specifications, but you have ti experimenting wih to see how it works.

  • How to remove the point of my array

    Hi, I have a table with the elements. now, I want to remove all elements in the array. How can it be possible?

    It depends on what you mean by compensation. The delete operator sets an array to undefined element, the length of the array remains unchanged.

    for (var i: int = 0; i<=  yourarray.length();="">

    {

    delete [i] yourArray;

    }

  • The context of the menu hard drive problems - cannot remove the point of garbage

    When right click on a drive (icon in the Explorer...) upwards appears familiar context menu.  The mine this counts as an item listed in the menu: \REGISTRY\]USERS\S-1-5-21... (many more numbers and letters).

    I tried all the obvious stuff, including transplant, without successful surgery - looking for the above string is futile. Manually check each Drive\shellex\ContextMenuHandlers.  Note that all other menus are very well.

    How can I get rid of this, and more importantly, how did get there in the first place?

    A second problem of context has also been raised: no Winrar command is listed. Notta.  Again, tried the obvious shots including UN and re - install Winrar.  A touch of Winrar is curiously the ContextMenuHandlers for folder, etc.  Why can't I see the usual orders of Winrar?

    I look forward your answers :)

    Without a subject "MISTLETOE" here, I've chosen 'Performance'... hope this is correct.

    I found the answer: by using a context menu editor, I have disabled all non-microsoft components.  This fixes the problem with context menus HD (disk), but (as it turns out that) some file types have the same string of garbage in their menus!  While the rar, flv, txt

    cfg files do not have this problem, exe, jpg, gif etc. are not! I applied the same method for the shortcuts in the menu "files" context and voila, it worked.

    The offending program is of Stardock Iconpackager. HOW and WHY it has messed up my menus, I have no idea, but I would ask people to Stardock for a response.

    See you soon

  • Re: Remove the XP system restore point

    How can I remove an XP system restore point. In Oct 08 my PC date has been incorrectly defined on Nov 08 and System Restore creates different restore points. Now PC date set Oct 08 what will happen in November? Can I remove restore points?

    I think that you can't remove already created restore points ignore them. If your laptop is set correctly now I recommend you to create your own restore point and you will know which is the right one.

  • ChartCollection &amp; lt; Point &amp; gt; How to remove range?

    ChartCollection how to remove the beach? example: remove (index) (Point) remove

    Collections of table maintains a strictly growing range of data, which may be a treatment more effective because it ensures the middle values will not be changed or deleted. If the range to delete is at the beginning of the story, you can temporarily reduce Capacity to remove the items at the beginning; otherwise, the only way to remove items from a collection of table is to reset the entire collection.

    Since you're using a collection of points, it seems that you care only about the feature of change notification table collections, rather than guarantee the "strictly increasing range. In this case, you might want to use another collection such as notifying ObservableCollection as data source, or use a praise as data source List and manually Refresh the graph as the data changes.
