Control::Capture Property
Gets or sets a value indicating whether the control has captured the mouse.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
public: [BrowsableAttribute(false)] property bool Capture { bool get(); void set(bool value); }
When a control has captured the mouse, it receives mouse input whether or not the cursor is within its borders. The mouse is typically only captured during drag operations.
Only the foreground window can capture the mouse. When a background window attempts to do so, the window receives messages only for mouse events that occur when the mouse cursor is within the visible portion of the window. Also, even if the foreground window has captured the mouse, the user can still click another window, bringing it to the foreground.
When the mouse is captured, shortcut keys should not work.
The following code example demonstrates the Capture property. To run this example paste the following code in a form containing a Label named label1 and two ListBox controls named listbox1 and listbox2. Ensure the form and controls' MouseDown event is associated with the method in this example.
// This method handles the mouse down event for all the controls on the form. // When a control has captured the mouse // the control's name will be output on label1. void Control_MouseDown( System::Object^ sender, System::Windows::Forms::MouseEventArgs^ /*e*/ ) { Control^ control = (Control^)(sender); if ( control->Capture ) { label1->Text = control->Name + " has captured the mouse"; } }
for all windows to set this property value. Associated enumeration: UIPermissionWindow::AllWindows
