public WindowLayout()

Method Detail

minimumSize

public Dimension minimumSize(Container<GuiOutputManager> container)

Get the minimum size of the specified container.

Specified by:

minimumSize in interface LayoutManager<GuiOutputManager>

Parameters:

container - The container.

Returns:

Always null.

setDecorated

public void setDecorated(boolean decorated)

Set the decorated flag.

Parameters:

decorated - The window's decorated state.

doLayout

public void doLayout(Container<GuiOutputManager> container)

Place components in specified container.

Specified by:

doLayout in interface LayoutManager<GuiOutputManager>

Parameters:

container - Container to process - must be a window.

layoutRegular

private void layoutRegular(GuiWindow window)

Layouts a top-level gui window. This performs the layout when the window is in its CommonWindow.WINDOW_STATE_NORMAL or CommonWindow.WINDOW_STATE_MAXIMIZED states.

Parameters:

window - The window to layout.

layoutMinimized

private void layoutMinimized(WindowGuiImpl window)

Layouts a desktop-minimized top-level window. A window is desktop-minimized when its attribute SHOW-IN-TASKBAR is set to false and it is minimized using the minimized title bar button. In this state the window is not displayed in the task bar (note there is a Swing GUI limitation, see TODO) and so must stay on the desktop in a minimized form - only title bar visible resized to a minimal width.

Parameters:

window - The window to layout.

setMinimizedLocation

private void setMinimizedLocation(WindowGuiImpl wnd)

The method calculates a default window desktop-minimized location based on the location of previously desktop-minimized window. Desktop-minimized windows (in 4GL WINDOW:SHOW-IN-TASKBAR == false) "dock" in the bottom left corner of the active screen work area. The minimized windows are docked next to each other from left to right and from bottom up.

Parameters:

wnd - The subjected window.

getSlotsPerRow

private int getSlotsPerRow(WindowGuiImpl wnd)

Calculates the number of "slots" that fit the width of the screen. A slot is an area that fits a window that is minimized and not shown on the taskbar. The supplied window is used as a hint to get the correct display work area on multi-screen systems.

Parameters:

wnd - A window reference.

Returns:

number of slots
