Functions for wxGauge class
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

Summary
Functions
Creates the gauge for two-step construction.
Destructor, destroying the gauge.
Returns the maximum position of the gauge.
Returns the current position of the gauge.
Returns true if the gauge is vertical (has wxGA_VERTICAL
style) and false
otherwise.
Default constructor.
Constructor, creating and showing a gauge.
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.
Sets the range (maximum value) of the gauge.
Sets the position of the gauge.
Types
-type wxGauge() :: wx:wx_object().
Functions
-spec create(This, Parent, Id, Range) -> boolean() when This :: wxGauge(), Parent :: wxWindow:wxWindow(), Id :: integer(), Range :: integer().
-spec create(This, Parent, Id, Range, [Option]) -> boolean() when This :: wxGauge(), Parent :: wxWindow:wxWindow(), Id :: integer(), 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.
-spec destroy(This :: wxGauge()) -> ok.
Destructor, destroying the gauge.
Returns the maximum position of the gauge.
See: setRange/2
Returns the current position of the gauge.
See: setValue/2
Returns true if the gauge is vertical (has wxGA_VERTICAL
style) and false
otherwise.
-spec new() -> wxGauge().
Default constructor.
-spec new(Parent, Id, Range) -> wxGauge() when Parent :: wxWindow:wxWindow(), Id :: integer(), Range :: integer().
-spec new(Parent, Id, Range, [Option]) -> wxGauge() when Parent :: wxWindow:wxWindow(), Id :: integer(), 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
-spec pulse(This) -> ok when 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 getValue/1
is
undefined and thus you need to explicitly call setValue/2
if you want to
restore the determinate mode.
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
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.
