NAME
wxGauge - Functions for wxGauge class
DESCRIPTION
A gauge is a horizontal or vertical bar which shows a quantity (often
time).
wxGauge supports two working modes: determinate and indeterminate
progress.
The first is the usual working mode (see setValue/2 and setRange/2)
while the second can be used when the program is doing some processing
but you don't know how much progress is being done. In this case, you
can periodically call the pulse/1 function to make the progress bar
switch to indeterminate mode (graphically it's usually a set of blocks
which move or bounce in the bar control).
wxGauge supports dynamic switch between these two work modes.
There are no user commands for the gauge.
Styles
This class supports the following styles:
See: wxSlider, wxScrollBar
This class is derived (and can use functions) from: wxControl wxWindow
wxEvtHandler

DATA TYPES
wxGauge() = wx:wx_object()
EXPORTS
new() -> wxGauge()
Default constructor.
new(Parent, Id, Range) -> wxGauge()
Types:
Parent = wxWindow:wxWindow()
Id = Range = integer()
new(Parent, Id, Range, Options :: [Option]) -> wxGauge()
Types:
Parent = wxWindow:wxWindow()
Id = Range = integer()
Option =
{pos, {X :: integer(), Y :: integer()}} |
{size, {W :: integer(), H :: integer()}} |
{style, integer()} |
{validator, wx:wx_object()}
Constructor, creating and showing a gauge.
See: create/5
destroy(This :: wxGauge()) -> ok
Destructor, destroying the gauge.
create(This, Parent, Id, Range) -> boolean()
Types:
This = wxGauge()
Parent = wxWindow:wxWindow()
Id = Range = integer()
create(This, Parent, Id, Range, Options :: [Option]) -> boolean()
Types:
This = wxGauge()
Parent = wxWindow:wxWindow()
Id = Range = integer()
Option =
{pos, {X :: integer(), Y :: integer()}} |
{size, {W :: integer(), H :: integer()}} |
{style, integer()} |
{validator, wx:wx_object()}
Creates the gauge for two-step construction.
See new/4 for further details.
getRange(This) -> integer()
Types:
This = wxGauge()
Returns the maximum position of the gauge.
See: setRange/2
getValue(This) -> integer()
Types:
This = wxGauge()
Returns the current position of the gauge.
See: setValue/2
isVertical(This) -> boolean()
Types:
This = wxGauge()
Returns true if the gauge is vertical (has wxGA_VERTICAL style)
and false otherwise.
setRange(This, Range) -> ok
Types:
This = wxGauge()
Range = integer()
Sets the range (maximum value) of the gauge.
This function makes the gauge switch to determinate mode, if
it's not already.
When the gauge is in indeterminate mode, under wxMSW the gauge
repeatedly goes from zero to range and back; under other ports
when in indeterminate mode, the range setting is ignored.
See: getRange/1
setValue(This, Pos) -> ok
Types:
This = wxGauge()
Pos = integer()
Sets the position of the gauge.
The pos must be between 0 and the gauge range as returned by
getRange/1, inclusive.
This function makes the gauge switch to determinate mode, if it
was in indeterminate mode before.
See: getValue/1
pulse(This) -> ok
Types:
This = wxGauge()
Switch the gauge to indeterminate mode (if required) and makes
the gauge move a bit to indicate the user that some progress has
been made.
Note: After calling this function the value returned by get-
Value/1 is undefined and thus you need to explicitly call set-
Value/2 if you want to restore the determinate mode.
