pyui.set_on_click_handler - pytha-3d-cad/pytha-lua-api GitHub Wiki

Sets the on_click handler function for controls that support this event. The click event is usually invoked when the user clicks (presses and releases a pointing device) on the control.

pyui.set_on_click_handler(control, func)
control:set_on_click_handler(func)

Parameters

	Type	Description
`control`	`control_handle`	A control handle returned by one of the `pyui.create_xxx` control creation functions
`func`	`function`	A lua function that is invoked for every change event

Return value

Type	Description
`control_handle`	The `control` handle is returned again

Note:

This handler is specific to the current modal environment / dialog and can only be set within a dialog.

The parameters to the on_click handler differ slightly depending on the control on which it is used

function on_click_handler([state])

	Type	Description
`state`	`boolean`	The new state of the control (if applicable)

A useful pattern is to write the handler function inline

local text_box = pyui.create_text_box(2)
text_box:set_on_change_handler(function(text)
    -- do something with the new content: text
end)
