NAME
wxStatusBar - Functions for wxStatusBar class
DESCRIPTION
A status bar is a narrow window that can be placed along the bottom of a frame to give
small amounts of status information. It can contain one or more fields, one or more of
which can be variable length according to the size of the window.
wxStatusBar also maintains an independent stack of status texts for each field (see
pushStatusText/3 and popStatusText/2).
Note that in wxStatusBar context, the terms pane and field are synonyms.
Styles
This class supports the following styles:
Remark: It is possible to create controls and other windows on the status bar. Position
these windows from an OnSize() event handler.
Remark: Notice that only the first 127 characters of a string will be shown in status bar
fields under Windows 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.
See: wxStatusBarPane (not implemented in wx), wxFrame, Examples
This class is derived (and can use functions) from: wxWindow wxEvtHandler

DATA TYPES
wxStatusBar() = wx:wx_object()
EXPORTS
new() -> wxStatusBar()
Default ctor.
new(Parent) -> wxStatusBar()
Types:
Parent = wxWindow:wxWindow()
new(Parent, Options :: [Option]) -> wxStatusBar()
Types:
Parent = wxWindow:wxWindow()
Option = {winid, integer()} | {style, integer()}
Constructor, creating the window.
See: create/3
destroy(This :: wxStatusBar()) -> ok
Destructor.
create(This, Parent) -> boolean()
Types:
This = wxStatusBar()
Parent = wxWindow:wxWindow()
create(This, Parent, Options :: [Option]) -> boolean()
Types:
This = wxStatusBar()
Parent = wxWindow:wxWindow()
Option = {winid, integer()} | {style, integer()}
Creates the window, for two-step construction.
See new/2 for details.
getFieldRect(This, I) -> Result
Types:
Result =
{Res :: boolean(),
Rect ::
{X :: integer(),
Y :: integer(),
W :: integer(),
H :: integer()}}
This = wxStatusBar()
I = integer()
Returns the size and position of a field's internal bounding rectangle.
Return: true if the field index is valid, false otherwise.
See: {X,Y,W,H}
getFieldsCount(This) -> integer()
Types:
This = wxStatusBar()
Returns the number of fields in the status bar.
getStatusText(This) -> unicode:charlist()
Types:
This = wxStatusBar()
getStatusText(This, Options :: [Option]) -> unicode:charlist()
Types:
This = wxStatusBar()
Option = {number, integer()}
Returns the string associated with a status bar field.
Return: The status field string if the field is valid, otherwise the empty string.
See: setStatusText/3
popStatusText(This) -> ok
Types:
This = wxStatusBar()
popStatusText(This, Options :: [Option]) -> ok
Types:
This = wxStatusBar()
Option = {number, integer()}
Restores the text to the value it had before the last call to pushStatusText/3.
Notice that if setStatusText/3 had been called in the meanwhile, popStatusText/2
will not change the text, i.e. it does not override explicit changes to status text
but only restores the saved text if it hadn't been changed since.
See: pushStatusText/3
pushStatusText(This, String) -> ok
Types:
This = wxStatusBar()
String = unicode:chardata()
pushStatusText(This, String, Options :: [Option]) -> ok
Types:
This = wxStatusBar()
String = unicode:chardata()
Option = {number, integer()}
Saves the current field text in a per-field stack, and sets the field text to the
string passed as argument.
See: popStatusText/2
setFieldsCount(This, Number) -> ok
Types:
This = wxStatusBar()
Number = integer()
setFieldsCount(This, Number, Options :: [Option]) -> ok
Types:
This = wxStatusBar()
Number = integer()
Option = {widths, [integer()]}
Sets the number of fields, and optionally the field widths.
setMinHeight(This, Height) -> ok
Types:
This = wxStatusBar()
Height = integer()
Sets the minimal possible height for the status bar.
The real height may be bigger than the height specified here depending on the size
of the font used by the status bar.
setStatusText(This, Text) -> ok
Types:
This = wxStatusBar()
Text = unicode:chardata()
setStatusText(This, Text, Options :: [Option]) -> ok
Types:
This = wxStatusBar()
Text = unicode:chardata()
Option = {number, integer()}
Sets the status text for the i-th field.
The given text will replace the current text. The display of the status bar is
updated immediately, so there is no need to call wxWindow:update/1 after calling
this function.
Note that if pushStatusText/3 had been called before the new text will also replace
the last saved value to make sure that the next call to popStatusText/2 doesn't
restore the old value, which was overwritten by the call to this function.
See: getStatusText/2, wxFrame:setStatusText/3
setStatusWidths(This, Widths_field) -> ok
Types:
This = wxStatusBar()
Widths_field = [integer()]
Sets the widths of the fields in the status line.
There are two types of fields: fixed widths and variable width fields. For the
fixed width fields you should specify their (constant) width in pixels. For the
variable width fields, specify a negative number which indicates how the field
should expand: the space left for all variable width fields is divided between them
according to the absolute value of this number. A variable width field with width
of -2 gets twice as much of it as a field with width -1 and so on.
For example, to create one fixed width field of width 100 in the right part of the
status bar and two more fields which get 66% and 33% of the remaining space
correspondingly, you should use an array containing -2, -1 and 100.
Remark: The widths of the variable fields are calculated from the total width of
all fields, minus the sum of widths of the non-variable fields, divided by the
number of variable fields.
See: setFieldsCount/3, wxFrame:setStatusWidths/2
setStatusStyles(This, Styles) -> ok
Types:
This = wxStatusBar()
Styles = [integer()]
Sets the styles of the fields in the status line which can make fields appear flat
or raised instead of the standard sunken 3D border.
