Icon bar widgets

class Sisyphe.widgets.iconBarViewWidgets.IconBarWidget(parent: QWidget | None = None)

IconBarWidget class

Description

Base class that encapsulates a primary view widget (typically a MultiViewWidget subclass) and enhances it with a collapsible, vertical icon bar.

The main features are as follows:

Encapsulated view widget access: the python __call__ syntax where he instance can be called like a function (e.g. instance_name()) returns the native encapsulated view widget. This is a fast and easy way to access all the methods of the encapsulated view widget.
Collapsible icon bar: a space-saving icon bar is displayed on the left. It automatically hides when the mouse is over the main view and reappears when the mouse pointer moves to the left edge. This behavior can be overridden by “pinning” the bar to keep it permanently visible.
Standardized Toolset: The icon bar provides quick access to a rich set of common functionalities, grouped into icons:
- View control: fullscreen mode, expanding a single sub-view, and zoom controls (in, out, reset).
- Display settings: menus for toggling the visibility of on-screen elements like the cursor, information text, orientation markers, color bars, and rulers.
- Interactive tools: menus for managing mouse interaction modes, adding measurement tools (e.g. distance, angle), and configuring isolines.
- Capture: buttons to save the current view(s) to a bitmap file or copy them directly to the system clipboard.
Context-sensitive menus: menus associated with icons are dynamically populated based on the state of the encapsulated view widget. For example, the “Isoline” menu lists all displayed volumes and overlays available for contouring.
Drag-and-Drop integration: fully supports dragging volumes from an external source (like a thumbnail bar) and dropping them onto the view. The drop behavior (e.g., replace the current volume, add as an overlay, or prompt the user) is configurable through application settings (settings.xml).
Customizable interface: offers an extensive API to control the visibility and availability of each button on the icon bar, allowing derived classes to tailor the user interface to their specific needs.
