+## Adding a Swing component to CFD composition using SwingPanel.
+
+SwingPanel lets you create a UI using Swing components in a Compose-based UI. To achieve this you need to create Swing component and pass it as a parameter to SwingPanel.

+## Methods
+
+Using the following methods, you can change the state of the AppWindow:
+
+1. show(parentComposition: CompositionReference? = null, content: @Composable () -> Unit) – shows a window with the given Compose content,
+`parentComposition` is the parent of this window's composition.
+2. close() - closes the window.
+3. minimize() - minimizes the window to the taskbar. If the window is in fullscreen mode this method is ignored.
+4. maximize() - maximizes the window to fill all available screen space. If the window is in fullscreen mode this method is ignored.
+5. makeFullscreen() - switches the window to fullscreen mode if the window is resizable. If the window is in fullscreen mode `minimize()` and `maximize()` methods are ignored.
+6. restore() - restores the normal state and size of the window after maximizing/minimizing/fullscreen mode.
+
+You can know about window state via properties below:
+
+1. isMinimized - returns true if the window is minimized, false otherwise.
+2. isMaximized - returns true if the window is maximized, false otherwise.
+3. isFullscreen - returns true if the window is in fullscreen state, false otherwise.
