Step by Step solution about How to resolve the algorithm GUI/Maximum window dimensions step by step in the Go programming language

Explanation:

This Go program uses the robotgo library to interact with the user's desktop and manage windows. It performs the following tasks:

1. Getting Screen Size:

   • The program initially determines the screen's dimensions using robotgo.GetScreenSize(). It prints these dimensions to the console.

2. Finding Firefox Window:

   • The program searches for windows with titles containing "firefox" using robotgo.FindIds("firefox"). If such windows are found, it proceeds to work with the first one (indicated by fpid[0]).

3. Activating and Maximizing Firefox Window:

   • The program activates the found Firefox window using robotgo.ActivePID(pid) and maximizes it using robotgo.MaxWindow(pid).

4. Getting Max Usable Size:

   • After maximizing the Firefox window, the program retrieves its new dimensions using robotgo.GetBounds(pid) and prints them to the console. This represents the maximum usable area of the Firefox window on the user's screen.

5. Printing Results:

   • The program prints the following information to the console:
     • Screen size
     • Max usable area of the maximized Firefox window

How to Use:

1. Install the robotgo library:

   • go get -u github.com/go-vgo/robotgo

2. Run the program:

   • go run main.go

Note: This program requires permissions to control the user's desktop and windows. Grant the necessary permissions when prompted.

package main

import (
    "fmt"
    "github.com/go-vgo/robotgo"
)

func main() {
    w, h := robotgo.GetScreenSize()
    fmt.Printf("Screen size: %d x %d\n", w, h)
    fpid, err := robotgo.FindIds("firefox")
    if err == nil && len(fpid) > 0 {
        pid := fpid[0]
        robotgo.ActivePID(pid)
        robotgo.MaxWindow(pid)
        _, _, w, h = robotgo.GetBounds(pid)
        fmt.Printf("Max usable : %d x %d\n", w, h)
    }
}
