BUILT-IN MATHEMATICA SYMBOL

LocatorPane

LocatorPane[{x, y}, back]
represents a pane with a locator at position and background back.

LocatorPane[Dynamic[pt], back]
takes the locator position to be the dynamically updated current value of pt, with the value of pt being reset if the locator is moved.

LocatorPane[{pt₁, pt₂, ...}, back]
sets up multiple locators at positions , , ....

LocatorPane[Dynamic[{pt₁, pt₂, ...}], back]
takes the locator positions to be dynamically updated current values of the .

LocatorPane[pts, back, {{x_min, y_min}, {x_max, y_max}}]
specifies the range of coordinates for the locator.

LocatorPane[pts, back, {{x_min, y_min}, {x_max, y_max}, {dx, dy}}]
uses jumps dx, dy.

Details and Options Details and Options

The background in a locator pane can be a graphic or any other expression.
For a Graphics object g, LocatorPane[pt, g] by default takes the range of coordinates for pt to be the range of graphics coordinates corresponding to PlotRange in g.
For a general expression, LocatorPane[pt, expr] takes the range of coordinates for pt to be 0 to 1 in each direction.
The following options can be given:

Appearance	Automatic	the appearance of locators
AutoAction	False	whether to move the locator automatically when the mouse is over it
BaselinePosition	Automatic	how to align with a surrounding text baseline
BaseStyle	{}	base style specifications for the locator pane
ContinuousAction	True	whether to update continuously when locators are moved
Enabled	Automatic	whether the locator pane is enabled, or its locators are grayed out
Exclusions	{}	specific points to exclude
LocatorAutoCreate	False	whether to allow clicks to create new locators
TouchscreenAutoZoom	False	whether to zoom to fullscreen when activated on a touchscreen

With the setting Appearance->g, all locators in the locator pane are displayed as g, where g is any graphic or other expression. »
With Appearance->{g₁, g₂, ...}, the i locator is displayed as . »
LocatorPane[{pt₁, pt₂, ...}, back, {range₁, range₂, ...}] specifies different ranges for different locators.
LocatorPane[pts, back, range] by default directs any click to the nearest locator.
The settings for BaseStyle are appended to the default style typically given by the style in the current stylesheet.
