How to get the actual size of control?

Similar Questions

• Questions regarding the process of implementing container/control. How "parent of filling" and how to get the actual size of the control?

  I'm writing some UI component custom waterfalls. I went if the document several times and still have two questions:

  1. is it possible to adjust the width of the control to fill the container parent without specifying the number hardcoded in pixel? I see many example of code uses '768' as hardcoded width.

  2. I understand that the 'preferred size' could be ignored in some cases. Is it possible that I can get the actual size of the control on the screen programmatically?

  3. is there any signal was issued when a control container/finish covering all of its child nodes? How do I know what size of a control is finally decided?

  Thank you

  (1) you can use (QML)

  horizontalAlignment: HorizontalAlignment.Fill
  

  or (C++)

  myControl->setHorizontalAlignment(HorizontalAlignment::Fill);
  

  This will cause control occupy the entire width available to its parent. However, keep in mind you may have to use this property on all containers of parent to the node root to get the width of the full screen.

  As far as I KNOW simon_hain is located on the other two issues.

  ((2) & (3) I just dug around and you find LayoutUpdateHandler would do the job:

  mdodd answer on question 1) is correct.

  I can't believe they made a separate category for such a common task. Framework of stunts have had some serious consistency problems, that's what I feel.

• Cascades - how to get the actual size of the item?

  Hi all

  Is it possible to get the actual width/height of the Visual element in cascade? I developed before Qt Quick applications and Qt Quick solution was simple - there's width and height properties which was always updated to the size of the real thing, and you could use them when necessary. In Silverlight, there are ActualHeight() and ActualWidth() for all visible elements. However, in the Cascades, as I see it, there are only minHeight, maxHeight, and preferredHeight and the same width, but there is no property that references element real width or height.

  I need, for example, to assign the size appropriate to the ListView items - I want to create horizontal ListView which shows only a single element (that is, the image) at a time, correctly resizes this image to fit, and works for a screen resolution and orientation. Qt Quick, I solved this by linking the width and the height to the width of the container of the element of the list element and (Rectangle) height of ListView and using the good snapMode (i.e. SnapOneItem). This works perfectly for any screen size & resolution. How can I do something like this in stunts without Hardcoding the 'magic numbers' preferredWidth and preferredHeight?

  Thanks in advance for your answer.

  You can get the width and height by using LayoutUpdateHandler of the element:

  https://developer.BlackBerry.com/Cascades/reference/bb__cascades__layoutupdatehandler.html

  LayoutUpdateHandler::create(scrollView)
      .onLayoutFrameChanged(this, SLOT(handleLayoutFrameUpdated(QRectF)));
  

• How can I get the actual size of an element in a photo?

  HI -.

  I was responsible for providing the actual measurements of the elements in the photographs. (There are 300 different photos, so I hope we find a pretty direct solution).

  My thought process was to open a photo, drag a bounding box around the document with the tool of the mark and read the precautions in the Info Panel.  But it does not work too well.

  
  

  In the sake of discussion, let's say I have a picture of a simple, plastic, badge/toy type 'happy meal '.  The insignia is actually 1 "squares.

  When I drag the box around it the Panel Info tells me that it measures W:3.37 "X H:3.37".

  ' ' I can't figure out how to get l: 1 "x H:1" to appear in the Info Panel.

  Dimensions of the photo show a massive 66 "x 44" at 72 dpi, and it seems that all 300 of these photos have the same dimensions, so one solution it should all.

  So the question is - using Photoshop, how to learn the physical measures of an element in a photo?

  I thought that this should be simple, but it turns out to be a real headache.

  Any expert TIA of entry.

  You open the dialog box Image size (Ctrl Alt i or Cmd Opt i on a Mac).  Make sure that resampling is _not_ checked and the width is defined in inches.  Now do a little math:

  Size of your choice as 3.37 in. is indicated in your case, but you know that the actual size is 1 inch, multiply all that is in the field of the resolution of 3.37

  So if it's 72 resolution must be 242.64

  Make this change and OK it

  Drag another sample around the badge to check that the right size now.

  Don't forget: Re-sample must be disabled in the Image Size dialog box.

• How to get the physical size of the screen?

  Hi all

  How to get the physical width and height of the screen (not resolution) in inches or in centimeters?

  Is there a method to do

  Thank you very much

  Display.getWidth () and Display.getHeight () you will get the number of pixels.

  Display.getHorizontalResolution (); and Display.getVerticalResolution () to get the pixels per meter.  Then by dividing appropriately you can find the actual size.

• How to get the 'description' of a control property if the control is a part of the cluster?

  Hi, dear all

  LV offers the possibility to work with the property 'description' of the individual control of the VI. The use of knots of property: reference VI > front propert > control [] property > Description.

• How to get the real size of the screen?

  Hi all

  I want to get the size of the BACKGROUND object screen AREA.

  I tried to call

  my_main_screen.getMainManager () .getVirtualWidth ();

  or

  my_main_screen.getMainManager () .getVisibleWidth ();

  But they always return 0.

  How to get this size? Thank you!

  Hey there. You can summarize this article:

  sector screen explained

  then you replace in your test screen

   protected void onUiEngineAttached(boolean attached) {
          String width = String.valueOf(getMainManager().getWidth());
          String height = String.valueOf(getMainManager().getHeight());
          Dialog.alert(width + " : " + height);
      }
  

  That you will get the result. On my 9630 Simulator, I saw the following values for the width and height: 480 and 333 respectively.

  I hope it works for you.

  Anyone know how to see what is the total size of the article before you download? I have an article that contains the video and several pages. I know I'm next above the limit, but I can't see how. I know that you can see the total link but surely Indesign, it's self will add more info on which will increase the size? I checked the video and pictures and they seem to fall under the 200 MB for the article. That article is not big so I need to know what is the total amount.

  I hope someone can help!

  (B) the limit is 100 MB for an article.

  That's really low, when you add videos to your article, so I hope they will change that in the future!

• How to get the original size of pictures? Microsoft office Picture Manager

  I used household image and all my photos are made smaller, but now I want size beck to original size. How can I do?

  You can enlarge the current versions of the photos
  in the photo... Manager using custom or
  Options of percentage but there is no way to return
  to the original version in Office Picture Manager.
  Extended versions is not the same quality
  than the originals.

  Info about photo manager
  If you resize a photo with Picture Manager and
  save it when you see the dialog box saying:

  "There are changes that have not been saved"

  The original photo will be overwritten (replaced)
  with the rezized version... IOW the original will
  be unrecoverable.

  To keep two versions of the picture, resize it
  and go... File / save as... Enter a new name for
  version resized and on the left, click on the "Save" button.

  When you close the photo manager and see the
  dialog box:

  "There are changes that have not been saved"

  On the left, click the do not save"" button. Now

• How to get the form of Boolean control LED (round or square) in Labview 8.6?

  Well, it's pretty simple...

  Can be any kind of response, error, errors, Style ID anything.

  But I can't seem to find an answer.

  Help, please

  Running of the tests here there seems to work

  Thanks for the help

  For one who also has to wonder how do:

  -First download the script from this link and follow the instructions to activate scripiting.

  https://decibel.NI.com/content/docs/doc-4973

  -After that, the Style ID will appear as a property on the property node

  -ID 21012 style is round LED and the 21013 is the square LED

  Also even if you do not have the active script and you have a VI recorded with the property Style ID node, you can copy and paste into your VI and who still works

• How can I know the actual size of the type in a document of intent 'web '?

  I'm designing a document for iPhone 6plus pixels (1334 x 750) and need to know how translates the size. For example, when I call a text 30 PT., in the real world on the iPhone it's something much smaller than this... maybe 12 pt. This has something to with the number of pixels in the canvas... but how to convert?

  So, how to calculate the actual size of the type? I'm not good at math, I need to be told how to do it.

  For the output and display at 100%, InDesign defines the physical size of a pixel as "1/72, so the relationship between the print type size and displayed size of the iPhone is a simple report. For the iPhone6 72/326 Gets the relative size of the print to display discount, and 326/72 would be a multiplier. So to display 12pt type how it would print, set it to 54.4 pt (12 x 4.53). Or, to view a 1 inch by 1 inch square, resize it 453%.

  For the iPhone6 more the multiplier is 401/72 or 5.57

  }

  Above is my project simple as3 in flex builder 3.

  My screen resolution is 1920 * 1080, when debugging, the SWF is stretched to the full EI client area, but the stage.stageWidth is 500 and the stage.stageHeight is 375, stage.widht and stage.height are 0, who can tell me why and how to get the right size of the SWF, named the area size customer of EI in this situation?

  Thank you very much!

  The HTML wrapper can resize the SWF later, so wait a frame and recheck stageWidth/stageHeight.

• How to get the maximum disk size for a powershell prompt

  Hi guys

  I tried all day to get the value of the maximum disk size allocated to a virtual machine. Using get - view I can see the actual size of disc but when I look at VM via 'Edit Machine' I see ' hard disk 1' ability to 40 GB and and size maximum (GB) to 97.5 - How do I get this maximum size via powershell?

  See you soon

  Sparky

  Near there, it is actually the amount of free space on the data store over the current size of the hard drive.

  With this script, you can calculate the value

  foreach($dev in (Get-VM  | Get-View).Config.Hardware.Device){
    if($dev.DeviceInfo.Label -like "Hard Disk*"){
      $dsFree = (Get-Datastore (Get-View -Id $dev.Backing.Datastore).Info.Name).FreeSpaceMB
       $diskSize = ($dev.CapacityInKB / 1Kb)
       $MaxSize = $dsFree + $diskSize
       Write-Host "Maximum size for" $dev.DeviceInfo.Label "=" ("{0:f2}" -f (($dsFree + $disksize)/ 1Kb)) "Gb"
    }
  }
