[−][src]Struct pushrod::widget::image_button_widget::ImageButtonWidget
Draws an image in a box with specified Text
next to it.
Methods
impl ImageButtonWidget
[src]
pub fn new(
font_name: String,
text: String,
image_name: String,
font_size: u32,
justify: TextJustify
) -> Self
[src]
font_name: String,
text: String,
image_name: String,
font_size: u32,
justify: TextJustify
) -> Self
Constructor. Requires the name of the font, the text to display, the image name to display, the size of the font,
and the font justification when rendered. Images are loaded from the assets/
directory.
pub fn on_click<F>(&mut self, callback: F) where
F: FnMut(&mut ImageButtonWidget) + 'static,
[src]
F: FnMut(&mut ImageButtonWidget) + 'static,
Sets a callback closure that can be called when a click is registered for this widget.
pub fn click(&mut self)
[src]
Calls the click on_click
callback, if set. Otherwise, ignored. Sends a reference
of the current Widget
object as a parameter, so this object can be modified when
a click is registered, if necessary.
Trait Implementations
impl Drawable for ImageButtonWidget
[src]
fn draw(&mut self, c: Context, g: &mut GlGraphics, clip: &DrawState)
[src]
fn draw_with_offset(
&mut self,
c: Context,
g: &mut GlGraphics,
clip: &DrawState,
point_offset: Point
)
[src]
&mut self,
c: Context,
g: &mut GlGraphics,
clip: &DrawState,
point_offset: Point
)
Draws an object at an offset on the screen. This is a convenience method that is used by other Widget
s that contain multiple widgets. Draw with offset always uses 0x0 as the starting drawing coordinates, as this is what will be drawn within the bounds of the Widget
. (See CheckboxWidget
and ImageButtonWidget
for good examples of this use.) Read more
impl InjectableSystemEvents for ImageButtonWidget
[src]
fn inject_system_event(&mut self) -> Option<CallbackEvent>
[src]
Part of the main loop that queries the Widget
for any system-level events that should be injected into the PushrodCallbackEvents
trait, and not handled by the top-level run loop. This sends out messages that are bypassed from being used by the Run Loop, so be very careful. Use this for sending things like custom messages (such as a Widget
move or Widget
resize message, which is irrelevant to the run loop.) Read more
impl InjectableCustomEvents for ImageButtonWidget
[src]
fn inject_custom_event(&mut self, _widget_id: i32) -> Option<CallbackEvent>
[src]
Injects an event into the run loop. This can be a timer event, a refresh event, or whatever the Widget
wants to inject. These should be custom events, not system events. This method only gets called if injects_events
returns true
. Read more
impl Widget for ImageButtonWidget
[src]
fn config(&mut self) -> &mut Configurable
[src]
fn set_config(&mut self, config: u8, config_value: Config)
[src]
fn handle_event(
&mut self,
injected: bool,
event: CallbackEvent,
_widget_store: Option<&Vec<WidgetContainer>>
) -> Option<CallbackEvent>
[src]
&mut self,
injected: bool,
event: CallbackEvent,
_widget_store: Option<&Vec<WidgetContainer>>
) -> Option<CallbackEvent>
fn handles_events(&mut self) -> bool
[src]
fn set_widget_id(&mut self, widget_id: i32)
[src]
fn get_widget_id(&mut self) -> i32
[src]
fn get_injectable_custom_events(&mut self) -> &mut dyn InjectableCustomEvents
[src]
fn get_injectable_system_events(&mut self) -> &mut dyn InjectableSystemEvents
[src]
fn get_drawable(&mut self) -> &mut dyn Drawable
[src]
fn invalidate(&mut self)
[src]
Indicates that a Widget
object needs to be repainted.
fn clear_invalidate(&mut self)
[src]
Clears the invalidation flag. Set this when the draw
function completes. Otherwise, this Widget
object may be continuously repainted. Read more
fn is_invalidated(&mut self) -> bool
[src]
Indicates whether or not a Widget
needs to be repainted.
fn get_config(&mut self, config: u8) -> Option<&Config>
[src]
Master config getter - use convenience methods.
fn set_point(&mut self, config: u8, x: i32, y: i32)
[src]
Sets a point value for a configuration key.
fn set_size(&mut self, config: u8, w: i32, h: i32)
[src]
Sets a size value for a configuration key.
fn set_color(&mut self, config: u8, color: Color)
[src]
Sets a color for a configuration key.
fn set_numeric(&mut self, config: u8, value: u64)
[src]
Sets a numeric value for a configuration key.
fn set_text(&mut self, config: u8, text: String)
[src]
Sets a text value for a configuration key.
fn set_toggle(&mut self, config: u8, flag: bool)
[src]
Sets a toggle value for a configuration key.
fn injects_custom_events(&mut self) -> bool
[src]
If this Widget
provides custom injected events that are generated outside of the handle_event
loop, indicate true
. Only override if necessary. (See TimerWidget
for reference.) Read more
fn is_drawable(&mut self) -> bool
[src]
Describes whether or not the Widget
returns a Drawable
trait. This function is called each time a frame is refreshed, so if there is no Drawable
available, this function could serve as a way to indicate a frame tick. Only override this to set it to false
if your Widget
does not draw anything on the screen. Read more
fn injects_system_events(&mut self) -> bool
[src]
Indicates to the run loop whether or not a Widget
injects system-level events.
