@class wxStatusBar

+ wxStatusBar also maintains an independent stack of status texts for each field

@beginStyleTable
- @style{wxST_SIZEGRIP}
- On Windows 95, displays a gripper at right-hand side of the status
- bar.
+ @style{wxSTB_SIZEGRIP}
+ Displays a gripper at the right-hand side of the status bar which can be used
+ to resize the parent window.
+ @style{wxSTB_SHOW_TIPS}
+ Displays tooltips for those panes whose status text has been ellipsized/truncated
+ because the status text doesn't fit the pane width.
+ Note that this style has effect only on wxGTK (with GTK+ >= 2.12) currently.
+ @style{wxSTB_ELLIPSIZE_START}
+ Replace the beginning of the status texts with an ellipsis when the status text
+ widths exceed the status bar pane's widths (uses wxControl::Ellipsize).
+ @style{wxSTB_ELLIPSIZE_MIDDLE}
+ Replace the middle of the status texts with an ellipsis when the status text
+ widths exceed the status bar pane's widths (uses wxControl::Ellipsize).

+ Replace the end of the status texts with an ellipsis when the status text

+ @remarks
+ It is possible to create controls and other windows on the status bar.
+ Position these windows from an OnSize() event handler.
+
+ @remarks
+ Notice that only the first 127 characters of a string will be shown in
+ status bar fields under pre-XP MSW systems (or even under later systems if
+ a proper manifest indicating that the program uses version 6 of common
+ controls library is not used). This is a limitation of the native control
+ on these platforms.
