Global FunctionUI and Dialogs

ImagePicker(key, label)

Creates an image picker component for dialogs.

Detailed Explanation

This section explains when to use the API, how to call it, and which structures it works best with in production flow.

What It Does

ImagePicker(key, label) performs one focused job in script flow and can be chained cleanly with other API steps. Creates an image picker component for dialogs.

When To Use It

In dialog and HUD flow, validate user input and complete the sequence with close/dispose steps to keep the UI stable. This API becomes most valuable in multi-step chained scenarios.

Parameters and Return

key, label define the purpose of the call; preparing them in clearly named variables before execution makes production debugging easier. The safest usage pattern is to store the call result in a variable, wrap it with pcall, and pass it into later steps in a controlled way.

Best Combined With

You can combine it with Setting.builder(), Dialog, Checkbox, EditText, Hud, and Console to build richer operator-facing flows.

Example Usage

The snippet below is a starter pattern that can be applied directly in runtime flow.

lua

ImagePicker("target", "Select target image")

Copyable Progressive Examples

From foundation to combined usage, each level is provided as a separate code block so you can copy the level you need and adapt it directly.

Foundation

Shows the shortest direct way to call the API.

Foundation

lua

ImagePicker("target", "Select target image")

Simple

Wraps the base call with minimal flow control.

Simple

lua

local stepOk = true
ImagePicker("target", "Select target image")
if stepOk then
  wait(200)
end

Practical Flow

A practical pattern for real macros with pcall, logging, and guards.

Practical Flow

lua

local ok, result = pcall(function()
  ImagePicker("target", "Select target image")
end)

if not ok then
  print("API step failed: ImagePicker(key, label)")
  requestStop()
end

Detailed

This level packages the API into a reusable helper with error reporting.

Detailed

lua

-- In dialog and HUD flow, validate user input and complete the sequence with close/dispose steps to keep the UI stable.
local function run_imagepicker_step()
  ImagePicker("target", "Select target image")
end

local ok, err = pcall(run_imagepicker_step)
if not ok then
  toast("Step failed")
  print(err)
end

Combined

Combines the API with related structures to form a more realistic workflow.

Combined

lua

local dialog = Setting.builder()
dialog:add("delay", EditText("500", 1, "Delay"))
dialog:add("enabled", Checkbox(true, "Enabled"))
Setting.setDialog(dialog:build())
Setting.show()
ImagePicker("target", "Select target image")
