CHtmlView类和焦点 [英] CHtmlView class and focus

问题描述

我有在MFC中编写的对话框应用程序。
对话框上有3个子控件。
2按钮（按钮1&按钮2）和HTML控件（从CHtmlView派生的类）
HTML控件已导航到具有2个复选框的HTML页面（复选框1和复选框2） 。

控制焦点的Z轴顺序应该是：
按钮1
按钮2
HTML控件，然后再次按钮1

当焦点转到HTML控件时。我想把它设置为复选框1&然后在按Tab键之后，它将被设置为复选框2.
但是当我按下选项卡时焦点在复选框2，我想将其设置为按钮1。

ie
我想要的焦点循环如下：按钮1 - >按钮2 - >在HTML控制中的复选框1 - > HTML控制中的复选框2 - >然后再次按钮1

问题：
当焦点设置为HTML控件时，它不会设置为复选框1，并且在焦点对准时按下选项卡后复选框2焦点不
返回按钮1。

让我知道如果问题不够描述，我会简化它。
感谢您的时间。

解决方案

我无法测试，但可以尝试将WS_EX_CONTROLPARENT样式添加到HTML控制。

  int OnInitDialog（...）
 {
 HWND html = GetDlgItem ID_HTML）; 
 DWORD ex_style = GetWindowLong（html，GWL_EXSTYLE）; 
 SetWindowLong（html，GWL_EXSTYLE，ex_tyle | WS_EX_CONTROLPARENT）; 
 return 0; 
} 
  

我希望它能工作。

I am having Dialog Box Application written in MFC. Dialog is having 3 child controls on it. 2 Buttons (Button 1 & Button 2) and a HTML Control (Class derived from CHtmlView) HTML Control has been navigated to a HTML page having 2 checkboxes (Check Box 1 & Check Box 2).

Control Z-Order for focus should be like: Button 1 Button 2 HTML Control then again Button 1

When focus goes to HTML Control. I want it to set to Check Box 1 & then after pressing tab it will be set to Check Box 2. But When I press tab while the focus in on Check Box 2, I want it to set to Button 1.

i.e. I want focus cycle like : Button 1 -> Button 2 -> Check Box 1 in HTML Control -> Check Box 2 in HTML Control -> then again Button 1

Problem: When the focus is set to HTML Control, it doesn't get set to Check Box 1 and after pressing tab while focus is on Check Box 2 focus doesn't come back to Button 1.

Let me know if question is not descriptive enough, I will simplify it more. Appreciate your time.

解决方案

I can't test it but you may try to add the WS_EX_CONTROLPARENT style to the HTML control.

int OnInitDialog(...)
{
   HWND html = GetDlgItem(dialog, ID_HTML);
   DWORD ex_style = GetWindowLong(html, GWL_EXSTYLE);
   SetWindowLong(html, GWL_EXSTYLE, ex_tyle | WS_EX_CONTROLPARENT);
   return 0;
}

I hope it works.
