Element with Edner in the canvas uses Edgar's visual evaluation, and places a thumb in a specific place of the decorated element. is. I would like to click on the adonant, preview the canvas preview mouse-left buttondown element and get the underlying element inside the adornor. But in this case I get main window as ESOs. Could you please help? I'm a newbie in WPF. 

  Public class connector Edward: Adornor {private readonly connector thumb _thumb; Private Readonly Visual Collection _ Visual; Public Connector Edner (UIElement Beautified Element): Base (Decorated Element) {Focusable = True; _ Visual = new visual evaluation (this); _thumb = new connector thumb (); _thumb.Background = Brush Transpain; _visuals.Add (_thumb); } Secure Override Size Arrange Override (Size Final Size) {Double elHeight = AdornedElement.DesiredSize.Height; Double Edender Width = desired size. Wide; Double ederHeight = desired size. Light; _thumb.Arrange (New Rectangle (0, -Highight / 2, Brilliant Width, AdornerHeight)); Return final size; } Protected Override Visual Genetical Choled (Int Index) {Returns _Visals [Index]; } Protected override int visual billrink count {get {return_visuals.Count; }}} Size of public squares: UserControl {Private AdornerLayer _adornerLayer; Public size () {width = 50; Height = 50; Background = brush Tomato; Sector Area = New Thickness (2); Borderbrush = brush Black; this. Loaded + = overloaded; } Private Zero Onloaded (Object Sender, Routing Avenues Areas Attentor) {_adornerLayer = AdornerLayer.GetAdornerLayer (this); If (_adornerLayer! = Faucet) {Connector Edwardner = New Connector Edenner (this); _adornerLayer.Add (adorner); }}} Public square connector thumb: thumb {public connector thumb (width) = {width = 20; Height = 20; Background = brush. Transparent; Foreground = brush Black; Border zone = new thickness (1); IsHitTestVisible = True; }} Public Partial Class Main Window: Window {Private Zero OpenViewUp Life Button (Object Sender, Mousebutton and Evergus E) {// I want to get Connect here ..}}    < P>  Canvas.ZIndex  property on the elements. This will ensure that the elements are layered in the way you want.

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
