Un-minimizing an app with Applescript

Question

I'm trying to write a script to un-minimize an app that was previously minimized to dock. Problem is, I can't find the relevant property. I've tried miniaturized and collapsed but neither the window nor the process seems to have those?

The app I use (for testing) is Zipeg, a free packing tool.

I've also tried to click the button which happily MINIMIZES the app, but gives me an error when running on an already minimized app to restore it, probably because no window is visible. This script is below.

tell application "System Events"
    tell process "Zipeg"
        click button 1 of window 1
    end tell
end tell

The script I used to list properties is below.

tell application "System Events"
    tell process "Zipeg"
        get properties
        tell window 1
            get properties
        end tell
    end tell
end tell

Any ideas?

Answer 1

tell app (path to frontmost application as text)
    try
        set miniaturized of windows to false -- most apps
    end try
    try
        set collapsed of windows to false -- Finder
    end try
end tell

This unminimizes a single window if Minimize windows into application icon isn't checked:

try
    tell app "System Events" to tell process "Dock"
        click (last UI element of list 1 where role description is "minimized window dock item")
    end tell
end try

If all windows of an app are minimized, reopen unminimizes the first one:

tell app "TextEdit"
    reopen -- unminimizes the first minimized window or makes a new default window
    activate -- makes the app frontmost
end tell

Answer 2

if you tell application "App" to activate it will un-minimize a window if all windows are minimized.
