I have a borderless window that I want to be able to show and hide from the main app window. When I show it (it's called from a menu item) the focus shifts to the borderless window. To close it, I have to click to get focus on the main window, then click again to open the menu so I can select the hide item. The borderless window is set to stay on top of the main app window.
How do I keep focus on the main app window even while the borderless window is open?
The code for showing/hiding the borderless window:
private: System::Void previewMenuItem_Click(System::Object^ sender, System::EventArgs^ e) {
if (!previewWnd->open) {
previewWnd->open = true;
previewWnd->Visible = true;
previewMenuItem->Enabled = false;
stopPreviewMenuItem->Enabled = true;
}
}
private: System::Void stopPreviewMenuItem_Click(System::Object^ sender, System::EventArgs^ e) {
if (previewWnd->open) {
previewWnd->open = false;
previewWnd->Visible = false;
previewMenuItem->Enabled = true;
stopPreviewMenuItem->Enabled = false;
}
} |

The code for adding the borderless window to the main app:
public ref class Form1 : public System::Windows::Forms::Form {
private:
Preview ^previewWnd;
public:
Form1(void)
{
InitializeComponent();
previewWnd = gcnew Preview;
//
//TODO: Add the constructor code here
//
}
I'm not sure what to put in the destructor, since Preview.h has a destructor in it already:
protected:
///
/// Clean up any resources being used.
///
~Form1()
{
if (components)
{
delete components;
}
}
.
.
