}Expand description
Defines the methods implemented by all window widgets. More details can be found in the wiki. Windows (which can be found in the window module) implement GroupExt as well.
Safety
fltk-rs traits depend on some FLTK internal code
Warning
fltk-rs traits are non-exhaustive,
to avoid future breakage if you try to implement them manually,
use the Deref and DerefMut pattern or the widget_extends! macro
Required Methods
fn center_screen(self) -> Self where
Self: Sized,
fn center_screen(self) -> Self where
Self: Sized,
Positions the window to the center of the screen
fn make_modal(&mut self, val: bool)
fn make_modal(&mut self, val: bool)
Makes a window modal, should be called before show
fn fullscreen(&mut self, val: bool)
fn fullscreen(&mut self, val: bool)
Makes a window fullscreen
fn make_current(&mut self)
fn make_current(&mut self)
Makes the window current
Sets the windows icon. Supported formats are bmp, jpeg, png and rgb.
fn set_cursor(&mut self, cursor: Cursor)
fn set_cursor(&mut self, cursor: Cursor)
Sets the cursor style within the window. Needs to be called after the window is shown
fn set_border(&mut self, flag: bool)
fn set_border(&mut self, flag: bool)
Sets whether the window has a border
fn free_position(&mut self)
fn free_position(&mut self)
Frees the position of the window
fn raw_handle(&self) -> RawHandle
fn raw_handle(&self) -> RawHandle
Get the raw system handle of the window
unsafe fn set_region(&mut self, region: Region)
unsafe fn set_region(&mut self, region: Region)
Iconifies the window. You can tell that the window is iconized by checking that it’s shown and not visible
fn fullscreen_active(&self) -> bool
fn fullscreen_active(&self) -> bool
Returns whether the window is fullscreen or not
fn decorated_w(&self) -> i32
fn decorated_w(&self) -> i32
Returns the decorated width
fn decorated_h(&self) -> i32
fn decorated_h(&self) -> i32
Returns the decorated height
Set the window’s minimum width, minimum height, max width and max height. You can pass 0 as max_w and max_h to allow unlimited upward resize of the window.
Set the hotspot widget of the window
Set the shape of the window. Supported image formats are BMP, RGB and Pixmap. The window covers non-transparent/non-black shape of the image. The image must not be scaled(resized) beforehand. The size will be adapted to the window’s size
fn set_cursor_image(&mut self, image: RgbImage, hot_x: i32, hot_y: i32)
fn set_cursor_image(&mut self, image: RgbImage, hot_x: i32, hot_y: i32)
Set the cursor image
fn default_cursor(&mut self, cursor: Cursor)
fn default_cursor(&mut self, cursor: Cursor)
Set the window’s default cursor
fn screen_num(&self) -> i32
fn screen_num(&self) -> i32
Get the screen number
fn set_screen_num(&mut self, n: i32)
fn set_screen_num(&mut self, n: i32)
Set the screen number
fn wait_for_expose(&self)
fn wait_for_expose(&self)
wait for the window to be displayed after calling show().

fn set_opacity(&mut self, val: f64)
fn set_opacity(&mut self, val: f64)
Set the window’s opacity, Ranges from 0.0 to 1.0, where 1.0 is fully opaque and 0.0 is fully transparent. This should be called on a shown window. On X11, opacity support depends on the window manager and can be queried:
$ xprop -root _NET_SUPPORTED | grep -o _NET_WM_WINDOW_OPACITYfn set_xclass(&mut self, s: &str)
fn set_xclass(&mut self, s: &str)
Set the window’s XA_WM_CLASS property. This should be called before showing the window
fn clear_modal_states(&mut self)
fn clear_modal_states(&mut self)
Clear the modal state of the window
fn set_override(&mut self)
fn set_override(&mut self)
removes the window border and sets the window on top, by settings the NOBORDER and OVERRIDE flags
fn is_override(&self) -> bool
fn is_override(&self) -> bool
Checks whether the OVERRIDE flag was set
fn force_position(&mut self, flag: bool)
fn force_position(&mut self, flag: bool)
Forces the position of the window
fn set_icon_label(&mut self, label: &str)
fn set_icon_label(&mut self, label: &str)
Set the icon label
fn icon_label(&self) -> Option<String>
fn icon_label(&self) -> Option<String>
Get the icon label
