Usage #

These are the various api calls and are subject to change in the future.

Hide the desktop title bar

When you do this you will loose drag window functionality. (But there is a solution for that below). On Windows you also loose default resize and tool bar buttons (see below)

WindowUtils.hideTitleBar();

// If used on app launch wrap it this way:
WidgetsBinding.instance.addPostFrameCallback(
   (_) => WindowUtils.hideTitleBar(),
);

no_title

Show the default title bar

This will also give you options on customizing the default toolbar in the future

WindowUtils.showTitleBar();

Close the window

Required to implement if you hide the title bar

This executes a close command to the window. It can still be restored by the OS if enabled.

WindowUtils.showTitleBar();

Minimize the window

WINDOWS ONLY

Required to implement if you hide the title bar

This will minimize the window if you hide the title bar and/or have a custom minimize button.

WindowUtils.minWindow();

Maximize the window

WINDOWS ONLY

Required to implement if you hide the title bar

This will maximize the window if you hide the title bar and/or have a custom maximize button.

WindowUtils.maxWindow();

Center the window

This will center the window.

WindowUtils.maxWindow();

Set the window position

This will position the window in relation to the display it is rendered in.

You need to provide Offset that is the top left corner of the screen. You can get the current offset by calling WindowUtils.getWindowOffset().

WindowUtils.setPosition(Offset offset);

Set the window size

This will size the window in relation to the display it is rendered in.

You need to provide Size that is the width and height of the screen. You can get the current size by calling WindowUtils.getWindowSize().

WindowUtils.setSize(Size size);

Drag the window

Required to implement if you hide the title bar

This will drag the window. You can call this to move the window around the screen and pass the mouse event to the native platform.

WindowUtils.startDrag();

Drag to resize the window

This will drag resize the window. You can call this to resize the window on the screen and pass the mouse event to the native platform.

You need to provide DragPosition to tell the native platform where you are dragging from.

enum DragPosition {
  top,
  left,
  right,
  bottom,
  topLeft,
  bottomLeft,
  topRight,
  bottomRight
}

Included in the package is import 'package:window_utils/window_frame.dart'; a WindowsFrame that includes the calls for you with a transparent border to handle the events. See the example for more details.

startResize(DragPosition position);

Double tap title bar command

Required to implement if you hide the title bar

This will call the native platform command for when you double tap on a title bar.

WindowUtils.windowTitleDoubleTap();

Child window count

This will return a int count of all the children windows currently open.

WindowUtils.childWindowsCount();

Get display screen size

This will return a Size size of the display window that the application is running in.

WindowUtils.getScreenSize();

Get application screen size

This will return a Size size of the application window that is running.

WindowUtils.getWindowSize();

Get application position

This will return a Offset offset of the application window that is running.

WindowUtils.getWindowOffset();

Set Mouse Cursor

MACOS ONLY

Update the system cursor.

You need to provide CursorType type to set the cursor too. (You can also add the cursor to the stack)

Avaliable cursors:

enum CursorType {
  arrow,
  beamVertical,
  crossHair,
  closedHand,
  openHand,
  pointingHand,
  resizeLeft,
  resizeRight,
  resizeDown,
  resizeUp,
  resizeLeftRight,
  resizeUpDown,
  beamHorizontial,
  disappearingItem,
  notAllowed,
  dragLink,
  dragCopy,
  contextMenu,
}

WindowUtils.setCursor(CursorType cursor);

Add Mouse Cursor To Stack

MACOS ONLY

Add a new cursor to the mouse cursor stack.

You need to provide CursorType type to set the cursor too. (You can also add the cursor to the stack)

Avaliable cursors:

enum CursorType {
  arrow,
  beamVertical,
  crossHair,
  closedHand,
  openHand,
  pointingHand,
  resizeLeft,
  resizeRight,
  resizeDown,
  resizeUp,
  resizeLeftRight,
  resizeUpDown,
  beamHorizontial,
  disappearingItem,
  notAllowed,
  dragLink,
  dragCopy,
  contextMenu,
}

WindowUtils.addCursorToStack(CursorType cursor);

Remove Cursor From Stack

This will remove the top cursor from the stack.

WindowUtils.removeCursorFromStack();

Hide Cursor(s)

This will hide the all the cursors in the stack.

WindowUtils.hideCursor();

Reset Cursor

This will reset the system cursor.

WindowUtils.resetCursor();

Show Cursor(s)

This will show all the cursors in the stack.

WindowUtils.showCursor();
