NAME

6       wxGauge - Functions for wxGauge class
7

DESCRIPTION

9       A  gauge  is a horizontal or vertical bar which shows a quantity (often
10       time).
11
12       wxGauge supports  two  working  modes:  determinate  and  indeterminate
13       progress.
14
15       The  first  is  the  usual working mode (see setValue/2 and setRange/2)
16       while the second can be used when the program is doing some  processing
17       but  you  don't know how much progress is being done. In this case, you
18       can periodically call the pulse/1 function to  make  the  progress  bar
19       switch  to indeterminate mode (graphically it's usually a set of blocks
20       which move or bounce in the bar control).
21
22       wxGauge supports dynamic switch between these two work modes.
23
24       There are no user commands for the gauge.

26       Styles

30       See: wxSlider, wxScrollBar
31
32       This class is derived (and can use functions) from: wxControl  wxWindow

94
95              See new/4 for further details.
96
97       getRange(This) -> integer()
98
99              Types:
100
101                 This = wxGauge()
102
103              Returns the maximum position of the gauge.
104
105              See: setRange/2
106
107       getValue(This) -> integer()
108
109              Types:
110
111                 This = wxGauge()
112
113              Returns the current position of the gauge.
114
115              See: setValue/2
116
117       isVertical(This) -> boolean()
118
119              Types:
120
121                 This = wxGauge()
122
123              Returns  true if the gauge is vertical (has wxGA_VERTICAL style)
124              and false otherwise.
125
126       setRange(This, Range) -> ok
127
128              Types:
129
130                 This = wxGauge()
131                 Range = integer()
132
133              Sets the range (maximum value) of the gauge.
134
135              This function makes the gauge switch  to  determinate  mode,  if
136              it's not already.
137
138              When  the  gauge is in indeterminate mode, under wxMSW the gauge
139              repeatedly goes from zero to range and back; under  other  ports
140              when in indeterminate mode, the range setting is ignored.
141
142              See: getRange/1
143
144       setValue(This, Pos) -> ok
145
146              Types:
147
148                 This = wxGauge()
149                 Pos = integer()
150
151              Sets the position of the gauge.
152
153              The pos must be between 0 and the gauge range as returned by ge‐
154              tRange/1, inclusive.
155
156              This function makes the gauge switch to determinate mode, if  it
157              was in indeterminate mode before.

160
161       pulse(This) -> ok
162
163              Types:
164
165                 This = wxGauge()
166
167              Switch  the  gauge to indeterminate mode (if required) and makes
168              the gauge move a bit to indicate the user that some progress has
169              been made.
170
171              Note:  After  calling  this  function the value returned by get‐
172              Value/1 is undefined and thus you need to explicitly  call  set‐
173              Value/2 if you want to restore the determinate mode.
