QUESTION

How do I get the height and width from a DockPanel?

Asked 2019-Aug-21 at 04:28

I am using a DockPanel to host some image enhancement controls. The image to be enhanced is in the 'center' dock position. I would like to have the image fill the entire area of the DockPanel. I have a custom class that implements the WPF Canvas control and takes a windows.Rect as input. This Rect will set the area for the image render function which I have overridden.

I have tried to get the DockPanel.ActualHeight and .ActualWidth. both are NaN and the DockPanel.Width and Height = 0.

At the point of the construction of MainWindow, the child controls within the Window, in your case BaseDockPanel has not been loaded yet.

That is why you're getting a 0 for it's ActualWidth and ActualHeight.

What you can do is add an EventHandler for the Window's Loaded event as shown below.

QUESTION

Android - Accessing member variable from onTouchEvent()

Asked 2017-Apr-24 at 13:10

First I precise that I saw a lot of questions for similar issues, but no one for my exact case, so I have to ask my own question.

I'm trying to create an application that collect strokes when the user touches a view. I created a class named WritingView that extends View. In this class, I overrided the onTouchEvent() method to draw the strokes and collect the coordinates in an ArrayList named currentStroke. It works, until I try to access the content of the array that contains the coords in the MainActivity, when I click a button, where it is always empty.

Here is the code of the WritingView class, I give it all in case but I think the problem comes from onTouchEvent, the rest is here to draw the collecting canvas and the strokes on the screen, which works :

Seems you have 2 WritingViews. First you have one in your layout file, and you also create a new one in the Activity.
