Constructor Details

Window

public Window(Frame arg0)

Window

public Window(Window arg0)

Window

public Window(Window arg0,
 GraphicsConfiguration arg1)

Window

protected Window(com.vaadin.flow.component.Component peer,
 Window owner)

Owner-aware peer-injection seam, mirroring Dialog(com.vaadin.flow.component.Component, Window, String, Dialog.ModalityType). vaadinx.swing.JWindow threads its SJWindow peer plus an emulator-side owner through in one step — the public owner-taking ctors here can't be reused because they hardcode SWindow as the peer.

Window

protected Window(com.vaadin.flow.component.Component peer)

Window

protected <P extends com.vaadin.flow.component.Component>
Window(Class<P> peerType,
 Supplier<? extends P> peerFactory,
 Window owner)

The lazy form of Window(com.vaadin.flow.component.Component, Window): see Component(Class, Supplier). A factory that reads the owner's peer reads it when it runs, on the UI thread.

Window

protected <P extends com.vaadin.flow.component.Component>
Window(Class<P> peerType,
 Supplier<? extends P> peerFactory)

The lazy form: see Component(Class, Supplier).

Method Details

getLayout

public LayoutManager getLayout()

Overrides:

getLayout in class Container

setLayout

public void setLayout(LayoutManager mgr)

Stores the manager and invalidates as AWT does, minus the CSS dispatch — see windowLayout.

Overrides:

setLayout in class Container

Parameters:

mgr - may be null, as AWT allows

isOpaque

public boolean isOpaque()

Overrides:

isOpaque in class Component

isActive

public boolean isActive()

getOwner

public Window getOwner()

getLocale

public Locale getLocale()

Overrides:

getLocale in class Component

setSize

public void setSize(int width,
 int height)

R_swing_is_truth mirror: store the Swing-side size, push to the SWindow peer's width/height channel, fire COMPONENT_RESIZED when the value actually changed. Non-SWindow peers (JFrame's InlineStrategy / SJPanel) skip the peer write — an inline main window keeps its viewport-fill stance per D_inline_route_sizing; the field shadow + event still happen so user code sees consistent Swing state.

Overrides:

setSize in class Component

setSize

public void setSize(Dimension d)

Overrides:

setSize in class Component

dispose

public void dispose()

disposePeer

protected void disposePeer()

Tear down the peer in response to dispose(). Default delegates to SWindow.dispose() when the peer is an SWindow (the standard SFrame / SJFrame / SDialog path). Subclasses with non-SWindow peers — notably JFrame's InlineStrategy with an SJPanel peer — override to detach from the route's div. Called under the preventPeerEvents guard so a peer-originated OpenedChangeEvent doesn't double-fire WINDOW_CLOSING.

getShape

public Shape getShape()

getToolkit

public Toolkit getToolkit()

Overrides:

getToolkit in class Component

setLocation

public void setLocation(int x,
 int y)

R_swing_is_truth mirror of setSize(int, int) for placement: store, push to the SWindow peer's top/left channel (which takes the Dialog overlay out of its default centered position), fire COMPONENT_MOVED on actual change. Same non-SWindow-peer skip as setSize.

Overrides:

setLocation in class Component

setLocation

public void setLocation(Point p)

Overrides:

setLocation in class Component

setLocationByPlatform

public void setLocationByPlatform(boolean b)

Throws:

IllegalComponentStateException - if b and the window is already showing, as AWT's own body does before it stores

isAlwaysOnTop

public final boolean isAlwaysOnTop()

setAlwaysOnTop

public final void setAlwaysOnTop(boolean b)

setIconImages

public void setIconImages(List<? extends Image> icons)

addNotify

public void addNotify()

Overrides:

addNotify in class Container

removeNotify

public void removeNotify()

Overrides:

removeNotify in class Container

setMinimumSize

public void setMinimumSize(Dimension arg0)

Overrides:

setMinimumSize in class Component

reshape

public void reshape(int x,
 int y,
 int width,
 int height)

Deprecated AWT 1.0 alias — in the JDK this is the actual worker setBounds delegates to; we invert the delegation so the modern name carries the implementation.

Overrides:

reshape in class Component

setBounds

public void setBounds(int x,
 int y,
 int width,
 int height)

Place + size in one call. Fires up to two component events (MOVED then RESIZED), matching AWT's reshape behaviour of reporting each aspect that changed.

Overrides:

setBounds in class Component

setBounds

public void setBounds(Rectangle r)

Overrides:

setBounds in class Component

getLocation

public Point getLocation()

Overrides:

getLocation in class Component

getLocation

public Point getLocation(Point rv)

Overrides:

Overrides:

getSize in class Component

getSize

public Dimension getSize(Dimension rv)

Overrides:

getBounds

public Rectangle getBounds()

Overrides:

getBounds

public Rectangle getBounds(Rectangle rv)

Overrides:

getX

public int getX()

Overrides:

getX in class Component

getY

public int getY()

Overrides:

getY in class Component

getWidth

public int getWidth()

Overrides:

getWidth in class Component

getHeight

public int getHeight()

Overrides:

getHeight in class Component

setVisible

public void setVisible(boolean b)

Overrides:

setVisible in class Component

show

public void show()

Overrides:

show in class Component

hide

public void hide()

Overrides:

hide in class Component

applyVisibleToPeer

protected final void applyVisibleToPeer(boolean b)

Apply visibility to the peer in response to setVisible(boolean). Default delegates to SWindow.setVisible(boolean) when the peer is an SWindow (standard Dialog-backed shape); falls through to Component.setVisible(boolean) for non-SWindow peers as defensive coverage. Subclasses with bespoke peer-attach semantics — notably JFrame's InlineStrategy with an SJPanel peer attached to a route's div — override to substitute their own peer manipulation. Called under the preventPeerEvents guard so a peer-originated OpenedChangeEvent doesn't double-fire.

Overrides:

applyVisibleToPeer in class Component

blocksAfterVisibilityChange

protected boolean blocksAfterVisibilityChange(boolean b)

Whether the caller will block on a browser round-trip once this visibility change has been applied — true only for a modal Dialog.show(), which parks until the user answers. Decided on our side rather than the migrator's, which is what makes it answerable at all; the set is small and closed.

Parameters:

b - the visibility being applied, since only a show can be followed by a park

applyVisibleToPeerImpl

protected void applyVisibleToPeerImpl(boolean b)

The peer write itself, already on the UI thread and inside the preventPeerEvents guard. Subclasses with bespoke peer-attach semantics — notably JFrame's InlineStrategy with an SJPanel peer attached to a route's div — override this rather than applyVisibleToPeer(boolean), so the hop and the guard cannot be bypassed by forgetting to call super.

toFront

public void toFront()

postEvent

@Deprecated
public boolean postEvent(Event arg0)

Deprecated.

Specified by:

postEvent in interface MenuContainer

Overrides:

postEvent in class Component

toBack

Overrides:

setCursor in class Component

createBufferStrategy

public void createBufferStrategy(int arg0,
 BufferCapabilities arg1)
                          throws AWTException

Throws:

AWTException

createBufferStrategy

public void createBufferStrategy(int arg0)

getBufferStrategy

public BufferStrategy getBufferStrategy()

setOpacity

public void setOpacity(float arg0)

AWT's other two throws are not reproduced, and deliberately: both ask the platform whether it can do translucency at all — a browser can, so the answers would be "yes, supported" and the throws unreachable. What is declined is the peer push, so the window renders fully opaque.

Parameters:

arg0 - in [0, 1]

Throws:

IllegalArgumentException - outside that range, as AWT does

getBackground

public Color getBackground()

Overrides:

getBackground in class Component

setBackground

public void setBackground(Color arg0)

Overrides:

setBackground in class Component

paint

public void paint(Graphics arg0)

Overrides:

Overrides:

isValidateRoot in class Container

getAccessibleContext

public AccessibleContext getAccessibleContext()

Specified by:

getAccessibleContext in interface Accessible

Overrides:

getAccessibleContext in class Component

setLocationRelativeTo

public void setLocationRelativeTo(Component c)

AWT: null centers on screen, a visible component centers over that component. Both map to viewport-centering here — see SWindow.setLocationRelativeTo(Component) for the R_layouts_close_enough close-enough rationale. Clears the explicit-location shadow (the window is centered again, not at the last set coordinates); fires COMPONENT_MOVED only if an explicit placement was in effect, since a still-centered window didn't move.

isLocationByPlatform

public boolean isLocationByPlatform()

getOpacity

public float getOpacity()

setShape

public void setShape(Shape arg0)
