wxPopupTransientWindow::wxPopupTransientWindow | ( | wxWindow * | parent,
|  | int | flags = `wxBORDER_NONE` |
| ) |  |  |

Constructor.

## Member Function Documentation

virtual void wxPopupTransientWindow::Dismiss | ( |  | ) | `[virtual]`

Hide the window.

virtual void wxPopupTransientWindow::Popup | ( | wxWindow * | focus = `NULL` | ) | `[virtual]`

Popup the window (this will show it too).

If winFocus is non-NULL, it will be kept focused while this window is shown, otherwise this window itself will receive focus. In any case, the popup will disappear automatically if it loses focus because of a user action.

  Dismiss()

virtual bool wxPopupTransientWindow::ProcessLeftDown | ( | wxMouseEvent & | event | ) | `[virtual]`

Called when a mouse is pressed while the popup is shown.

Return true from here to prevent its normal processing by the popup (which consists in dismissing it if the mouse is clicked outside it).
