trait NetLogoListener extends EventListener
A host application should implement this interface in order to be notified of events occurring within NetLogo. Its methods are called by NetLogoListenerManager when these events occur. The events are typically user actions, but may also be triggered programmatically by the model.

def
buttonPressed(buttonName: String): Unit
Called when the user presses a button in the NetLogo model.
Called when the user presses a button in the NetLogo model.
Note that the button may take some time to run and therefore may not pop back up until some later. Use
buttonStopped()if you need to know when the button's action has completed. -
abstract
def
buttonStopped(buttonName: String): Unit
Called when a button in the NetLogo model has finished running and pops back up.
Called when a button in the NetLogo model has finished running and pops back up.
The button may be a "once" button or a "forever" button. If it is a "once" button, it pops back up automatically when its action is completed. If it is a "forever" button, it will pop back up when clicked for a second time by the user. (Some forever buttons may also pop back up automatically, if the model is written that way.)

def
chooserChanged(name: String, value: AnyRef, valueChanged: Boolean): Unit
Called when the value of a chooser changes.
Called when the value of a chooser changes. Usually if the chooser changes it is because the user has changed it using the mouse, but the change may also be the result of code in the model or code typed into the command center.
-
abstract
def
codeTabCompiled(text: String, errorMsg: CompilerException): Unit
Called when the Code tab is recompiled.
Called when the Code tab is recompiled.
- text
the contents of the Code tab
- errorMsg
message the user receives if there is a compiler error, or null
-
abstract
def
commandEntered(owner: String, text: String, agentType: Char, errorMsg: CompilerException): Unit
Called when the user enters text into the command center (and presses return).
Called when the user enters text into the command center (and presses return). Note that at the time this method is called, the command may not have finished executing yet.
- owner
name of the widget that owns the code
- text
the text the user entered
- agentType
O, T, or P depending whether the user was addressing the observer, turtles, or patches
- errorMsg
message the user receives if there is a compiler error, or null

def
inputBoxChanged(name: String, value: AnyRef, valueChanged: Boolean): Unit
Called when the value of an input box changes.
Called when the value of an input box changes. Usually if the input box changes it is because the user has changed it using the mouse, but the change may also be the result of code in the model or code typed into the command center.
-
abstract
def
modelOpened(name: String): Unit
Called when a model is opened.
Called when a model is opened.
- name
name of the model that was opened
-
abstract
def
possibleViewUpdate(): Unit
Called when the engine potentially schedules a view update.
Called when the engine potentially schedules a view update. "Potentially" because an actual update might not take place for any number of reasons (view updates are off, the speed slider is sped up, etc.).
-
abstract
def
sliderChanged(name: String, value: Double, min: Double, increment: Double, max: Double, valueChanged: Boolean, buttonReleased: Boolean): Unit
Called when the value of a slider changes.
Called when the value of a slider changes. Usually if the slider changes it is because the user has changed it using the mouse, but the change may also be the result of code in the model or code typed into the command center.
-
abstract
def
switchChanged(name: String, value: Boolean, valueChanged: Boolean): Unit
Called when the value of a switch changes.
Called when the value of a switch changes. Usually if the switch changes it is because the user has changed it using the mouse, but the change may also be the result of code in the model or code typed into the command center.
-
abstract
def
tickCounterChanged(ticks: Double): Unit
Called when the tick counter changes, either by being advanced, or by being reset to 0.
Called when the tick counter changes, either by being advanced, or by being reset to 0.
- ticks
new value of the tick counter
