Cannot click a control to allow input

[dasien]

Hello - I am using V 1.16 and running into the following issue. It is probably something i am doing wrong, so i pieced together some code from the larger project so that it can be run. If you run the code below, and press the "Show Detail" button, it will bring up a modal Dialog with several Views embedded in each other. The Combobox in the top right has focus, which I assume happens when i use the SetSource method on it. If i omit that call, the first TextField gets the focus. Using SetSource causes that focus to be on the ComboBox when the form is shown, which is odd. When i move the mouse around over any other Control, it seems like the ComboBoxcontrol with focus is getting all the mouse move events as well, because the cursor blinks (my cursor is set to block, so others' results may vary) irregularly as the mouse is moving, as if it is processing mouse events, or at least aware of them.

At any rate, the biggest issue is that i cannot click on the TextField or ComboBox in the Frame labeled "URI List" to get focus. I can click on the Button controls in there and they respond, but the input fields will not take focus from a click. If i click into the TextField labeled "Authenticator Key (TOTP)" (input controls outside the Frame will take a click and get focus), and then press the Tab key, the TextField in the Frame gets focus and it works.

I think it must be something i am doing either in ordering the controls into the Views or maybe i need to handle mouse events in a custom way. Any ideas would be appreciated and thank you in advance for looking. Code below:

    static void Main(string[] args)

This is still stumping me. Any help would be appreciated.

Ok after a lot of digging I have found a solution for your problem.

  private new void SetupView()
  {
      InitializeComponent();

      // Initialize any list controls.
      InitializeLists();

      // Load controls with current data only.
      LoadView();

      // Set our main view to the view area of the parent view.
      base.DetailView = vwLogin;

      // Setup common view parts.
      base.SetupView();

+      fraURIList.FocusFirst();

+      // Optional - this restores the original form open focus view.  You will need to make this field protected or create a method on base that does this line
+      base.txtItemName.FocusFirst();
  }

Mouse clicking into FrameView working correctly again

[dasien]

Thank you so much! I would love to understand why this line of code was necessary, if you have time to explain it.

[tznind]

Unfortunately I don't know why this line is necessary. I could see that the issue basically fixed itself when focus entered the Frame view so I made that happen with the API.

There is probably a bug somewhere in the core library but your example code has too much going on in it to easily debug/understand state of controls. I tried to reproduce with a standalone simpler setup of Views but didn't get the same bug.

v1 is now in maintenence and development work is focused on v2, so I doubt we will ever get to the bottom of the root cause.

[BDisp]

I was checking what was going on with this problem and discovered two bugs. One in the ComboBox where, because we define the Source, it forces the focus even though it has not been selected. Another in the ScrollView where the background is not being cleaned, sometimes showing duplicate views, as shown in the image below.

Also if you notice the border is not being properly drawn in the upper right corner. I couldn't figure out why this is happening, but it can be resolved by calling Application.Refresh before view.Show().

		private void HandleDetailButtonClick ()
		{
			CustomDetailView view = new CustomDetailView ();

			// Show the view modal.
			view.Modal = true;
			// Ensures the border is refreshed before show
			Application.Refresh ();
			view.Show ();
		}

I also suggest that you use computed layout to position views instead of using absolute values. I know you used the wonderful TGD tool to create this project but it also provides the possibility to use Pos/Dim values for positioning and sizing. Enjoy it .
I will submit PR to fix these bugs.

[tznind]

Awesome detective work @BDisp! Thanks!

[BDisp]

After all, this bug also exists with the Wizards scenario. Only after moving the mouse does the screen refresh. I will also submit a PR with the fix.

Another issue you have on your project is you declare btnSave = new Button (); but you don't add it to any superview.

[dasien]

Thank you both for all the investigation on this. I figured setting the source must be the reason the combo box is getting focus, i got around that with a method in my base View that a child View could call to set the focus on that txtItemName after everything was setup.

The btnSave being there is just an artifact of me cutting code out of the actual project to piece together the example - i missed removing that.

Thanks again!
