UIArea
Area consisting of left, top, right, and bottom value.
Definition: UIArea.h:20

UIBitmap
A widget containing a bitmap (XBMP) which is set statically during compile time.
Definition: UIBitmap.h:21

UIBitmap::computePreferredSize
void computePreferredSize(U8G2 *display, UISize *preferredSize)
Generate the preferred size from the bitmap size.
Definition: UIBitmap.cpp:44

UIBitmap::render
UIArea * render(U8G2 *display, bool force)
A bitmap is only rendered if the rendering is forced, otherwise it never changes.
Definition: UIBitmap.cpp:22

UIBitmap::UIBitmap
UIBitmap(uint16_t width, uint16_t height, const uint8_t *bitmap, UIAlignment alignment, UIWidget *next=nullptr)
Create a bitmap with supplied alignment and potential successor.
Definition: UIBitmap.cpp:15

UIPoint
Representation of a point on the display.
Definition: UIPoint.h:9

UISize
Representation of a size, i.e.
Definition: UISize.h:9

UIWidget
Basic widget class, ancestor of all UI widgets.
Definition: UIWidget.h:36

UIWidget::preferredSize
UISize preferredSize(U8G2 *display)
Return the preferred size of this widget, will be called before a call to layout().
Definition: UIWidget.cpp:16

UIWidget::next
UIWidget * next
Pointer to the next widget on the same level.
Definition: UIWidget.h:65
