Adaptative view.
An adaptative view is a view that adapts automatically to screen resolution change.
There are several kinds of adaptative views, according to the policy that is adopted when the resolution changes. In the examples below, The screen is represented by the black rectangle and the world is the red square. If red dashed lines appears, it means that the world has been modified.
| Class | Example |
|---|---|
| gf::StretchView | 
|
| gf::FitView | 
|
| gf::FillView | 
|
| gf::ExtendView | 
|
| gf::ScreenView | 
|
|
inline |
Default constructor.
This constructor creates a default view of \((0, 0, 1000, 1000)\).
|
inlineexplicit |
Construct the view from a rectangle.
| rect | Rectangle defining the zone to display |
Construct the view from its center and size.
| center | Center of the zone to display |
| size | Size of the zone to display |
|
pure virtual |
Callback when the screen has just been resized.
| screenSize | The new size of the screen |
Implemented in gf::ScreenView, gf::ExtendView, gf::FillView, gf::FitView, and gf::StretchView.
| void gf::AdaptativeView::setInitialScreenSize | ( | Vector2u | screenSize | ) |
Set the initial screen size.
| screenSize | The initial size of the screen |
