CButton::GetCheck
Visual Studio 2005
Retrieves the check state of a radio button or check box.
int GetCheck( ) const;
The return value from a button control created with the BS_AUTOCHECKBOX, BS_AUTORADIOBUTTON, BS_AUTO3STATE, BS_CHECKBOX, BS_RADIOBUTTON, or BS_3STATE style is one of the following values:
| Value | Meaning |
|---|---|
| BST_UNCHECKED | Button state is unchecked. |
| BST_CHECKED | Button state is checked. |
| BST_INDETERMINATE | Button state is indeterminate (applies only if the button has the BS_3STATE or BS_AUTO3STATE style). |
If the button has any other style, the return value is BST_UNCHECKED.
CButton myButton;
// Create an auto 3-state button.
myButton.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_AUTO3STATE,
CRect(10,10,100,30), pParentWnd, 1);
// Set the check state to the next state
// (i.e. BST_UNCHECKED changes to BST_CHECKED
// BST_CHECKED changes to BST_INDETERMINATE
// BST_INDETERMINATE changes to BST_UNCHECKED).
myButton.SetCheck( ((myButton.GetCheck()+ 1 ) % 3) );
