I have a page that has two UIElements that need to be printed, one is a StackPanel and the other is a custom graph control for displaying test scores. The graph control could be any length based on the number of tests to display, so sometimes I will be able to fit both on one page and other times will need separate pages.
Printing them on separate pages works fine as I just set the UIElement to the pagevisual, the problem I am having is that I can't figure out how to combine them for printing on a single page. I tried creating a StackPanel in the codebehind and adding the elements to it, but since an element can only have one parent I have to create temporary objects to hold each one while I remove from the original parent and then give the temp to the new StackPanel. The problem is that after I do that all the bound data goes missing
Any ideas would be awesome! Thanks.
Instead of adding actual elements to the StackPanel for printing, you can create snapshots of those elements and add only images to the StackPanel. You can use the following method to created an Image from a UIElement:
public static Image CreateElementImage(UIElement element)
{
var bitmap = new WriteableBitmap((int)element.RenderSize.Width, (int)element.RenderSize.Height);
Array.Clear(bitmap.Pixels, 0, bitmap.Pixels.Length);
bitmap.Render(element, element.RenderTransform);
bitmap.Invalidate();
var result = new Image {Source = bitmap};
return result;
}
Or just put the image in a Canvas and then compare Canvas's height and image height to calculate number of pages.

Forgive me, I'm not a proper JS programmer and still getting my head around a lot of concepts.
Suppose one had a group of similar, 2-frame/2-state rollover movie clips nested inside a containing clip, which has the instance name "Map". Each clip uses a 4 digit ID number preceded by an "s" as an instance name – e.g., "s6566".
Suppose one then wanted to capture those respective instance names to define a variable, such that one small script could allow each of these movie clips to display their ID on rollover/active state (in this case "6566"), across multiple files.
Ultimately I have thousands of these little clips spread across several dozen documents, and it seems it should be fairly simple to grab each symbol's instance name/ID, strip off the "s" from the beginning (there because instance names can't begin with a numeral), and apply said ID as dynamic text to it's respective symbol's rollover/active frame.
Is there a method of achieving this goal? I wish I had some example code to include here, but I'm not quite sure how to begin, other than to lay out the problem thusly. Haven't yet been able to find any info on capturing instance names, and I'm not sure whether it's possible. Thanks.
Children of MovieClips are stored as references using their instance name. You can see the format in the exported library JS file. Note that Animate will convert some instance names to remove unsupported characters or duplicates.
Here is some untested pseudo-code to get you started.
// You can iterate a MovieClip and get the names
for (var name in someMovieClip) {
// Ignore anything not starting with an s
if (name.substr(0,1) != "s") { continue; }
// remove the s
var newName = name.substr(1);
// The child can be accessed using bracket-access with its name
var child = someMovieClip[name];
// The child should have text instances if it is set up how you described
// Set the text to the newName
child.textInstance.text = newName
}
Don't forget to update the stage after you make changes. If you already have Ticker set up to do that, it should update immediately.
I hope that helps. If you have follow-up questions, let me know.
When tableview is created, the default behaviour of columns is to leave a lot of empty space. Is there a way to automatically fill the space?
One solution is described here:
JavaFX 2 Automatic Column Width
but this seems a little cumbersome.
TornadoFX comes with an advanced column resize policy called SmartResize. You assign it to a TableView like this:
columnResizePolicy = SmartResize.POLICY
By default it tries to do something useful depending on the data, and it will assign any left over width to the last column.
You can configure resizing options per column by calling the appropriate configurator function. For example, to tell the policy to give remaining width to a given column:
column("Name", Person::nameProperty).remainingWidth()
You can configure multiple columns to receive remaning width, so that they will share the remaining width between them.
contentWidth() will make sure the column width fits the content, with optional additional padding: contentWidth(padding = 50.0).
Most resize options also take an optional useAsMin parameter which will enforce the given setting as a minimum width for the column. useAsMax does the same for max width. You will get a fixed size by setting both useAsMin and useAsMax or specifying the fixedWidth(width) option.
You can distribute space using the weigthedWidth(weightNum) function, or even the pctWidth(pctNum) function. All these modes can be combined
Please see the TornadoFX Guide chapter about the resize policy for more information:
When I move my mouse to a row in tree view and stay here for a second, I want to see a floating window. (Like in developer mode.)
How Can I solve it? Any idea?
When you declare your field or fields that get rendered on a listview make sure you give to the __init__ method the help='My Floating Test' argument. That will cause a floating window to be shown when you hover on that field.
For example check:
addons/account/models/account.py
tag_ids = fields.Many2many('account.account.tag', 'account_account_account_tag', string='Tags', help="Optional tags you may want to assign for custom reporting")
The string on the help attribu will be shown on all the views that render this field upon hovering on it and pausing for 1 second.
If you want to modify the window that is shown, you can extend the
t-name="WidgetLabel.tooltip" template that is located in addons/web/static/src/xml/base_common.xml
I am wondering if its possible to have a core data and use a NSFetchedResultsController to display template holders; without saving the placeholder template holder to core data.
I am writing an app where a table view will have the following characteristics
Maximum amount of rows (ie: 8)
Each cell uses a partial view, a single table cell instance with clickable buttons;
A user clicking on the buttons replaces the content for each button
When a user comes to save the data it stores the content in the exact places, but crucially it should not save the blank placeholder state; but still respect the placement positioning.
IE: Lets say a user picks the right button for cell 1 and saves it;
when the the user returns to this dataset sometime in the future, it
should have the imagery and data in the correct place; but still keep
the left button for cell 1 empty (placeholder)
The reason I don't want to save the placeholder content is because I consider this data to be "dirty"; its meaningless and has no place in a dataset; its a view; not data.
Currently:
I create data using insertInManagedObjectContext but do not save it until the user has pressed save.
Each matchRow has many fighters. This relationship is a NSOrderedSet, managed by core data.
The problems I'm having are;
NSFetchedResultsController only respects saved core data items; and ignores the placeholder data.
If a user only saves one (right button) data, the NSOrderedSet sees this as the first (left button) data; which is in correct
If I strip out all the placeholder structures from the core data in a pre-save action, the effect is that the order the user wanted is now lost and it causes a crash when reloading because the size of the arrays are incorrect.
Currently the only way around this is to stop using
NSFetchedResultsController and use a NSArray; and put the placeholders into the array too, then save everything, (dirty objects) and all.
I really don't want to do that. The placeholder content isn't meant to be saved.
I've been reading a blog post on using separate classes for special cases where he has different data sources; and uses the technique to separate class for the "empty" case, and to set it as the table view’s datasource when it's empty.
Whilst this is interesting, it only solves it for an empty case; when my requirement is that the partial view should handle all states; empty data and partial data.
One idea I have is that we need another entity between our record and our match rows;
Match - MatchRowMeta - Fighter
Not sure what the relationship would be
where;
RowMeta {
record.obj (relationship)
fighters.obj (relationship)
positionID (integer) - which button has been set
}
But I don't think this is the best way to do it; it seems expensive and a lot of heavy lifting to do something relatively simple.
Thus, my question:
Is it possible to have a table view made up of template holders; where the structure is saved to core data but none of the empty (dirty) objects are saved; plus NSFetchedResultsController will respect the structure; even when its empty or partially empty?
Edit: Added entity diagram
I want to use a WKInterfaceButton for my watch app, that looks like the buttons in the watch settings:
with two main attributes:
It should contain a small image on the left
its title should be aligned to the left
I didn't found any possibility to align the title of a button to the left. I already tried to use a group instead (then it would work), but when I use a group I can't use the the shape of WKInterfaceButton.
Here's how I would do it...
Create a button
Make that button type a group
Within that button-group, place two groups inside it. The group on the left will contain the image. The group on the right will contain a label
So place an image in the left group, and a label in the right group.
Adjust the margins, length, heights of these groups until you get the desired look.
Give the button-group a length relative to container of "1" and a height of "size to fit content"
For the inner group that will contain the image, give it a length of relative to container of "0.2" (maybe)
For the inner group on the right that will contain the label, give it a length of relative to container of "0.8" (so that together the two groups make 1)
Give both groups a height of relative to container (1)
use WKInterfaceButton Content as Group and place image and label in it.
While i haven't tried this myself i think what you're looking for to match the watch settings is a table view. Define a table view in the interface controller of your story board and add your image and label to the row(s). There's an example of how to do this in the programming guide for apple kit.
