Inheritance diagram for SoQtComponent:
Components in the SoQt component library all inherit this abstract base class. It provides basic methods for setting and querying about the relationship between the component object and its underlying Qt object(s).
Application programmers should not need to interface any code against this class, unless they want to extend the SoQt library in entirely new directions. For making new viewer components, for instance, other classes further down the inheritance hierarchy would be better suited for subclassing.
Note that the relationship between all SoQtComponent derived classes and Qt widgets is one of "has-A", not "is-A" -- i.e. SoQtComponent contains a QWidget *, it doesn't derive from or subclass it.

Destructor. |
|
This is a protected constructor, used only by derived classes.
The parent argument is the parent widget of the component. If you don't supply a parent, the main window (the one given to or returned from SoQt::init()) is used (and the embed argument is considered to be The name argument is the name of the component. If you don't supply one, the name will default to something, depending on the inheritance hierarchy.
The embed argument tells wether the component should be embedded in the parent widget or should create its own shell. This flag is only checked if the parent widget argument is specified (not If you create a non-embedded component, the component will create its own shell, which will be a toplevelshell type. If you embed the component, the component will create a formwidget type widget inside the parent widget, which you can get the handle of by calling SoQtComponent::getBaseWidget(). |
|
This function must be called by subclasses after the component's widget has been otherwise initialized. |
|
This will hide the widget.
|
|
Sets the cursor for this component. Note: not part of the original SGI InventorXt API. Reimplemented in SoQtFullViewer. |
|
Set cursor for a native widget in the underlying toolkit. Note: not part of the original SGI InventorXt API. |
|
Returns if this widget/component is in full screen mode. |
|
Toggle full screen mode for this component, if possible.
Returns |
|
Returns visibility status on the widget. If any parents of this widget or this widget itself is hidden, returns
Note that a widget which is just obscured by other windows on the desktop is not hidden in this sense, and
|
|
Returns
|
|
Returns a pointer to the component's window system widget.
|
|
An SoQtComponent may be composed of any number of widgets in parent-children relationships in a tree structure with any depth. This method will return the root widget in that tree.
|
|
This method returns the shell widget of the component, but only if it was created as a toplevel shell. (The toplevel shell is the desktop window which contains the component.) To get the toplevel shell of embedded components, you can use the SoQt::getShellWidget() method.
|
|
Returns the widget which is the parent (i.e. contains) this component's base widget.
|
|
Resize the component widget. The method assumes the caller knows what he is doing.
|
|
Returns the component widget size. The size that is returned is a cached size value, not a value fetched from the GUI system.
|
|
Set the window title of this component. The title will appear on the window title bar, if the component manages its own window. Note that there is one peculiarity to be aware of if you are using the non-commercial version of Qt: only window titles with the substring "Qt" in them are allowed (!), and attempts to set a window title without this substring will simply be ignored.
|
|
Returns the window title. If a title has been set, that title will be returned. If no title has been set, the default title is returned.
|
|
This method sets the title of the icon representation of the window. The title will appear on the window icon, if the component manages its own window.
|
|
Returns the title the window has when iconfied. If an icon title has been set, that icon title is returned. If no icon title has been set, the default icon title is returned.
|
|
Returns name of the widget. |
|
Returns class name of widget. |
|
Set up a callback function to use when the component gets closed. A component must be a toplevel shell for this to have any effect. For toplevel shells with no close callback set, the window will simply be hidden. The typical action to take in the callback would be to delete the component.
|
|
Finds and returns the SoQtComponent corresponding to the given QWidget *, if any. If the widget does not seem to belong to any SoQtComponent, |
|
This function initializes the type system for all the component classes. It is called indirectly for you when you call SoQt::init().
|
|
A function "hook" / callback invoked just after the window for the component has been realized. Override this if you need specific initialization for your own component or viewer class to happen right after it has been made visible, but remember to call upwards in the inheritance hierarchy:
void MyLittleViewer::afterRealizeHook(void) { <superclass>::afterRealizeHook(); // [own initialization here] } Reimplemented in SoQtRenderArea, SoQtPlaneViewer, SoQtExaminerViewer, and SoQtFlyViewer. |
|
Set class name of component.
|
|
Set the core widget for this SoQt component. It is important that subclasses get this correct, as the widget set here will be the widget returned from query methods.
|
|
This method should be used by subclasses to register the widgets they set up from the underlying native toolkit, so they can be "reverse" mapped to the owner component. Subclasses failing to register the widgets they use will cause the SoQtComponent::getComponent() method to fail with those widgets.
|
|
Remove a previously registered native toolkit widget from the widget-to-component mappings used by SoQtComponent::getComponent().
|
|
This method returns the default name of a component widget class. It should be overridden by derived non-abstract classes for the topmost widget in the component to have a proper name. Reimplemented in SoQtRenderArea, SoQtPlaneViewer, SoQtExaminerViewer, and SoQtFlyViewer. |
|
This method returns the default window caption string of the component. It should be overridden by derived non-abstract classes so the window and popup menu will get a proper title. Reimplemented in SoQtRenderArea, SoQtPlaneViewer, SoQtExaminerViewer, and SoQtFlyViewer. |
|
This method returns the default icon title of the component. It should be overridden by derived non-abstract classes so icons will get proper titles. Reimplemented in SoQtRenderArea, SoQtPlaneViewer, SoQtExaminerViewer, and SoQtFlyViewer. |
|
Called internally from within the SoQt library when the widget embedded in a component changes it size, which is usually triggered by end-user interaction. This method is then invoked to notify the component that the size has changed. It is called from the top and all the way down to the bottom, the size being adjusted to take into account extra decorations having been added at each level in the component class hierarchy. Reimplemented in SoQtGLWidget, SoQtRenderArea, SoQtViewer, and SoQtFullViewer. |
|
Add a callback which will be called whenever the widget component changes visibility status (because of iconification or deiconification, for instance).
|
|
Remove one of the callbacks from the list of visibility notification callbacks.
