🛡️ Safety Features

Move mouse to any corner of the screen to abort all automation.

# Enable failsafe (enabled by default)
dc = DesktopController(failsafe=True)

Pause Control

# Pause all automation for 2 seconds
dc.pause(2.0)

# Check if automation is safe to proceed
if dc.is_safe():
    dc.click(500, 500)

Approval Mode

---

🎨 Advanced Examples

Example 1: Automated Form Filling

dc = DesktopController()

# Click name field
dc.click(300, 200)
dc.type_text("John Doe", wpm=80)

# Tab to next field
dc.press('tab')
dc.type_text("[email protected]", wpm=80)

# Tab to password
dc.press('tab')
dc.type_text("SecurePassword123", wpm=60)

# Submit form
dc.press('enter')

# Capture specific area
region = (100, 100, 800, 600)  # left, top, width, height
img = dc.screenshot(region=region)

# Save with timestamp

timestamp = datetime.datetime.now().strftime("%Y%m%d_%H%M%S")
img.save(f"capture_{timestamp}.png")

Example 3: Multi-File Selection

# Hold Ctrl and click multiple files
dc.key_down('ctrl')
dc.click(100, 200)  # First file
dc.click(100, 250)  # Second file

Example 4: Window Automation

# Activate Calculator
dc.activate_window("Calculator")
time.sleep(0.5)

# Type calculation
dc.type_text("5+3=", interval=0.2)
time.sleep(0.5)

# Take screenshot of result
dc.screenshot(filename="calculation_result.png")

Example 5: Drag & Drop File

# Drag file from source to destination
dc.drag(
    start_x=200, start_y=300,  # File location
    end_x=800, end_y=500,       # Folder location
    duration=1.0                 # Smooth 1-second drag
)

⚡ Performance Tips

1. Use instant movements for speed: duration=0
2. Batch operations instead of individual calls
3. Cache screen positions instead of recalculating
4. Disable failsafe for maximum performance (use with caution)
5. Use hotkeys instead of menu navigation

---

⚠️ Important Notes

• Screen coordinates start at (0, 0) in top-left corner
• Multi-monitor setups may have negative coordinates for secondary displays
• Windows DPI scaling may affect coordinate accuracy
• Failsafe corners are: (0,0), (width-1, 0), (0, height-1), (width-1, height-1)
• Some applications may block simulated input (games, secure apps)

---

🔧 Troubleshooting

Mouse not moving to correct position

• Check DPI scaling settings
• Verify screen resolution matches expectations
• Use get_screen_size() to confirm dimensions

Keyboard input not working

• Ensure target application has focus
• Some apps require admin privileges
• Try increasing interval for reliability

Failsafe triggering accidentally

• Increase screen border tolerance
• Move mouse away from corners during normal use
• Disable if needed: DesktopController(failsafe=False)

Permission errors

• Run Python with administrator privileges for some operations
• Some secure applications block automation

---

📦 Dependencies

• PyAutoGUI - Core automation engine
• Pillow - Image processing
• OpenCV (optional) - Image recognition
• PyGetWindow - Window management

Install all:

pip install pyautogui pillow opencv-python pygetwindow
