A spin box control.
This control class is templated so that arbitrary data types can be used with Spin. All the built-in numeric types are supported by the code here. If you want to use some other type, such as an enum type, you need to define operator+(), operator-(), and template specializations of spin_details::mod() and spin_details::div(). Spin controls are optionally directly editable by the user. When the user inputs a value that is not valid for the Spin's parameters (not on a step boundary, or outside the allowed range), the input gets locked to the nearest valid value. The user is responsible for selecting a min, max, and step size that make sense. For instance, min = 0, max = 4, step = 3 may produce odd results if the user increments all the way to the top, then back down, to produce the sequence 0, 3, 4, 1, 0. To avoid this, choose the values so that (max

Returns the size of the minimum bounding box that can enclose the Wnd and still show all of its elements, plus enough room for interaction with those elements (if applicable). For example, a TextControl's MinUsableSize() is just the area of its text, and a Scroll's MinUsableSize() is the combined sizes of its up-button, down-button, and tab (plus a bit of room in which to drag the tab).

void GG::Spin< T >::Render | ( | ) | [virtual] |
Draws this Wnd. Note that Wnds being dragged for a drag-and-drop operation are rendered twice -- once in-place as normal, once in the location of the drag operation, attached to the cursor. Such Wnds may wish to render themselves differently in those two cases. To determine which render is being performed, they can call GUI::GetGUI()->RenderingDragDropWnds().

void GG::Spin< T >::SetValue | ( | T | value | ) |

void GG::Spin< T >::AllowEdits | ( | bool | b = true | ) |
turns on or off the mode that allows the user to edit the value in the spinbox directly.
void GG::Spin< T >::DefineAttributes | ( | WndEditor * | editor | ) | [virtual] |
Provides the attributes of this object that are appropriate for a user to edit in a WndEditor; see WndEditor for details.

void GG::Spin< T >::KeyPress | ( | Key | key, |

Flags< ModKey > | mod_keys | ||

Respond to down-keystrokes (focus window only). A window may receive KeyPress() messages passed up to it from its children. For instance, Control-derived classes pass KeyPress() messages to their Parent() windows by default.

void GG::Spin< T >::MouseWheel | ( | const Pt & | pt, |

Respond to movement of the mouse wheel (move > 0 indicates the wheel is rolled up, < 0 indicates down)

bool GG::Spin< T >::EventFilter | ( | Wnd * | w, |
const WndEvent & | event | ||
) | [protected, virtual] |
Handles an WndEvent destined for Wnd w, but which this Wnd is allowed to handle first. Returns true if this filter processed the message.
