grabFocus back to summary

grabFocus	back to summary
public boolean grabFocus() Grabs focus on this window. All mouse clicks that occur in this window's client area or client-areas of any of its unfocusable owned windows are delivered as usual. Whenever a click occurs on another app's window (not related via the ownership relation with this one, or a focusable owned window), or on non-client area of any window (titlebar, etc.), or any third-party app's window, or native OS GUI (e.g. a taskbar), the grab is automatically reset, and the window that held the grab receives the FOCUS_UNGRAB event. Note that for this functionality to work correctly, the window must have a focus upon calling this method. All owned popup windows that should be operable during the grabbed focus state (e.g. nested popup menus) must be unfocusable (see `setFocusable`). Clicking a focusable owned window will reset the grab due to a focus transfer. The click that occurs in another window and causes resetting of the grab may or may not be delivered to that other window depending on the native OS behavior. If any of the application's windows already holds the grab, it is reset prior to grabbing the focus for this window. The method may be called multiple times for one window. Subsequent calls do not affect the grab status unless it is reset between the calls, in which case the focus is grabbed again. Note that grabbing the focus on an application window may prevent delivering certain events to other applications until the grab is reset. Therefore, if the application has finished showing popup windows based on a user action (e.g. clicking a menu item), and doesn't require the grab any more, it should call the `ungrabFocus` method. The FOCUS_UNGRAB event signals that the grab has been reset. A user event handler associated with a menu item must be invoked after resetting the grab. Otherwise, if a developer debugs the application and has installed a breakpoint in the event handler, the debugger may become unoperable due to events blocking for other applications on some platforms. Returns:boolean `true` if the operation is successful Exceptions IllegalStateException: if the window isn't focused currently

setBounds back to summary

setBounds	back to summary
public void setBounds(float x, float y, boolean xSet, boolean ySet, float w, float h, float cw, float ch, float xGravity, float yGravity, float renderScaleX, float renderScaleY) Sets the window bounds to the specified values. Gravity values specify how to correct window location if only its size changes (for example when stage decorations are added). User initiated resizing should be ignored and must not influence window location through this mechanism. The corresponding correction formulas are: `x -= xGravity * deltaW` `y -= yGravity * deltaH` Parameters x:float the new window horizontal position, ignored if xSet is set to false y:float the new window vertical position, ignored if ySet is set to false xSet:boolean indicates whether the x parameter is valid ySet:boolean indicates whether the y parameter is valid w:float the new window width, ignored if set to -1 h:float the new window height, ignored if set to -1 cw:float the new window content width, ignored if set to -1 ch:float the new window content height, ignored if set to -1 xGravity:float the xGravity coefficient yGravity:float the yGravity coefficient renderScaleX:float new rendering scale, ignored if < 1 renderScaleY:float new rendering scale, ignored if < 1
