在同一个应用程序中,有一个窗口正在使用Direct3D SDK以每秒5帧的速度渲染某些图像的电影。现在,在渲染电影时,即在播放模式下,工具提示永远不会出现。我一暂停电影,工具提示就开始出现

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
  • 案例1:
作为解决方法,我对代码做了以下更改-

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
工具提示工具提示=新工具提示()

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
toolTip.InitialDelay=50

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
设置工具提示(控件,文本)

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
现在,只要我引入一个初始延迟,工具提示就会被渲染,而不管电影是否正在播放

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
  • 案例2:
如果我没有设置初始延迟,而是订阅控件的onmousehave事件,然后将上述两行代码显式地放在偶数处理程序中,那么工具提示也不会丢失。他们看起来很正常。但是,这不是显示工具提示的标准做法

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");

有人能纠正我在工具提示渲染中的错误吗?我使用的是.Net 2.0&C#。

D3D视频和工具提示都使用了覆盖层(我使用的屏幕捕获程序中,有多少因为这个原因而不捕获工具提示!);所以我相信你看到了一些来自D3D叠加的干扰

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
可能是视频在绘制工具提示,因为它是在播放过程中渲染的-所以工具提示在那里,你就是看不到它

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
然而,我很困惑,为什么设置初始延迟会突然使它工作起来!也就是说,InitialDelay控制工具提示第一次显示时应用于工具提示的延迟,因此它可能与更改工具提示获取要显示的覆盖曲面的方式有关

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
当然,我会使用它作为解决方法,而不是像另一个答案所说的那样,重复构建和分配工具提示,因为它可能会破坏资源

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
我会找到尽可能小的初始延迟,然后继续

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");
最后,我们在这里讨论的是什么版本的Windows和DX?还有几个其他的线程,开始和里面的GameDev链接,关于工具提示和DirectX的问题;并指出一个事实,这里发生的事情可能不仅仅是一点.Net的怪异

请参见上的工具提示组件(Windows窗体)。具体来说,请查看如何:在设计时在为Windows窗体上的控件设置工具提示

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");

您没有正确使用工具提示。您链接到的示例仅显示如何创建工具提示,而不是如何使用它。

根据您的情况修改此示例。应该有用。您应该设置所有这些属性

            // Create the ToolTip and associate with the Form container.
            ToolTip toolTip = new ToolTip();

            // Set up the delays for the ToolTip.
            toolTip.AutoPopDelay = 15000;
            toolTip.InitialDelay = 300;
            toolTip.ReshowDelay = 300;
            // Force the ToolTip text to be displayed whether or not the form is active.
            toolTip.ShowAlways = true;

            // Set up the ToolTip text for the Buttons
            toolTip.SetToolTip(this.button2, "TooltipText1");
            toolTip.SetToolTip(this.button3, "TooltipText2");

这不一定是Wiki。这不是创建工具提示的标准方法。从实际角度来看,MSDN示例是错误的。该示例仅说明如何将工具提示创建为控件,而不是如何将工具提示用作组件。您希望将其用作组件。
