Key modifier(s) used in the method. |
KeyDown is overridden in TCustomTabControl to handle use of the Tab key (VK_TAB) to change the active page in the tabbed control.
The Options property must contain the value nboKeyboardTabSwitch to enable the tab switching feature. Pressing Ctrl+Tab switches to the next page by incrementing the PageIndex value. Pressing Ctrl+Shift+Tab switches to the previous page by decrementing the PageIndex value.
If Key is not the VK_TAB virtual key code, the inherited method is called to handle the values in Key and Shift.
