我在基于MFC对话框的应用程序中创建了一个新对话框。新对话框包含5个控制按钮。
以下情况发生,我不明白为什么?
当我这样做时:
**只有当我想再次点击buttonX时,才需要执行第3步!为什么?? 我认为它与SetFocus()有关,但我不确定如何。
按钮IDC是: IDC_BACK_MEDIA_PRESS_BUTTON 1180 IDC_TOOLS_LEFT_RIGHT 1024 IDC_MEDIA_FOREWARD_BUTTON 1103 IDC_MEDIA_BACKWARD_BUTTON 1104 IDC_TOOLS_HOOD_BUTTON 2346
对话框属性为:
IDD_TOOLS_DIALOG DIALOGEX 0,0,51,218 STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU 标题“工具” FONT 8,“MS Shell Dlg”,400,0,0x1 开始 PUSHBUTTON“Media& Foreward”,IDC_MEDIA_FOREWARD_BUTTON,7,79,37,36,BS_MULTILINE PUSHBUTTON“& Media& BackWard”,IDC_MEDIA_BACKWARD_BUTTON,7,43,37,36,BS_MULTILINE PUSHBUTTON“Back Media Press”,IDC_BACK_MEDIA_PRESS_BUTTON,7,127,37,36,BS_MULTILINE |不是WS_VISIBLE PUSHBUTTON“Hood”,IDC_TOOLS_HOOD_BUTTON,7,7,37,36 PUSHBUTTON“左右”,IDC_TOOLS_LEFT_RIGHT,7,175,37,36 END
我尝试了不同的风格,如工具窗口,重叠,弹出窗口。它发生在所有情况下。
感谢您的帮助。

答案 0 :(得分:0)
我看到你正在用对话框内容填充视图。你把焦点放在对话框上吗?我认为这种神秘的行为只发生在对话框中的第一次鼠标点击(然后对话框获得焦点)。我只是猜测:)
