onError
Description
onError(self, err)
This is a custom event which gets triggered as soon as the program catches an error.
Returns
objectThe object in use
Usage
- Add an onError event to a program:
local basalt = require("basalt")
local main = basalt.createFrame()
local aProgram = main:addProgram():execute("rom/programs/shell.lua")
local function onProgramError(self, err)
local errFrame = main:addFrame()
:setSize(30, 10)
:setPosition("parent.w / 2 - self.w / 2", "parent.h / 2 - self.h / 2")
errFrame:addLabel()
:setPosition(2, 3)
:setSize("parent.w - 2", "parent.h - 3")
:setText(err)
errFrame:addButton()
:setPosition("parent.w", 1)
:setSize(1, 1)
:setText("X")
:onClick(function()
errFrame:remove()
end)
end
aProgram:onError(onProgramError)
In this example, a Program object is created, added to the mainFrame, and the "rom/programs/shell.lua" script is executed. The onError event is then attached to the program, and it will be triggered when the program catches an error. The event function, onProgramError, will create an error Frame displaying the error message and a button to close the error Frame.
