多个鼠标/鼠标/光标？ [英] Multiple mouse/mice/cursor?

问题描述

如何显示多个鼠标的另一个游标？
我有两个TMemos，两个键盘可以输入到它们各自的TMemo，2个鼠标，我需要2个光标。

How can I show another cursor for multiple mice? I have two TMemos, two keyboards which can type into their respective TMemo, 2 mice and I need 2 cursors those.

如果假设，我可以检测哪个鼠标是哪个。如何使我自己的光标与它一起。 （使用Delphi）
可能沿多点

If hypothetically, I can already detect which mouse is which. How can I make my own cursor to go along with it. (using Delphi) Possibly along the lines of Multipoint

作为替代，是否有任何软件可以渲染更多的一个光标。像 CPNMouse ？

as an alternative, is there any software which can render more that one cursor. Like CPNMouse?

编辑：
我发现我可以在windows中使用mouse_event函数，但是我还没有光标的可视化表示。

I found that I can use the mouse_event Function in windows, but I still don't have the visual representation of the cursor.

推荐答案

p>游标只是资源。以下是可以使用的标准游标的良好列表。 TControl定义可以设置为在给定控件上应使用的游标的游标属性。您还可以使用Screen.Cursor来控制整个应用程序光标。

Cursors are just resources. Here is a good list of the standard cursors that can be used. TControl Defines a cursor property that can be set to the cursor that should be used when over a given control. You can also use Screen.Cursor to control the entire application cursor.

要定义自定义光标，请使用以下代码。

To define a custom cursor you use the following code.

{$R MyCustomCursors.RES}

const
 crCustom1 = 1;
 crCustom2 = 2; 

...

  Screen.Cursors[crCustom1] := LoadCursor(hInstance, 'CUSTOM1');
  Screen.Cursors[crCustom2] := LoadCursor(hInstance, 'CUSTOM2');

...

Delphi默认不处理多个鼠标指针，但我怀疑大多数环境都不是。你提到的SDK是我在单个应用程序中同时使用多个鼠标时看到的唯一信息来源。但是它只是.NET的，所以使用它将需要Delphi Prism。

Delphi was not designed by default to deal with multiple mouse pointers, but the I suspect most environments are not. The SDK you mention is the only source of information I have seen on using multiple mice at the same time in a single application. It however is .NET only, so using it would require Delphi Prism.

如果你想滚动自己的支持多个鼠标，使用WM_INPUT的同样的伎俩可以用过的。 Windows将两个鼠标作为相同。您必须手动为第二个鼠标自定义绘制鼠标光标。

If you want to roll your own support for multiple mice the same trick of using WM_INPUT can can be used. Windows will treat both mice as the same. You will have to do custom painting of the mouse cursor by hand for the second mouse.
