Protected Member Functions | |
void | Resort (KrImNode *resortMe) |
Resort can be called if a node's depth has changed and it needs to move elsewhere in the list. | |
Friends | |
class | KrImageTree |
The class in not abstract -- it can be very useful to have a KrImNode that is used as a container for other objects.
Children always draw on top of their parents.
virtual KrImNode* KrImNode::Clone | ( | ) | [virtual] |
int KrImNode::NodeId | ( | ) | [inline] |
Any ImNode can have a name or id.
They are completely managed by the user -- they are not used by the engine in any way. They should be unique to the tree, and can be used as a way to keep track of nodes.
An empty name or an id<0 indicate no name and no id, respectively.
const std::string& KrImNode::NodeName | ( | ) | [inline] |
Any ImNode can have a name or id.
They are completely managed by the user -- they are not used by the engine in any way. They should be unique to the tree, and can be used as a way to keep track of nodes.
An empty name or an id<0 indicate no name and no id, respectively.
void KrImNode::ScreenToObject | ( | int | x, | |
int | y, | |||
grinliz::Vector2< GlFixed > * | object, | |||
int | window = 0 | |||
) |
Transform screen (pixel) coordinates to local object coordinates.
The composite Xform is used for this and must be initialized -- practically, the object must be in a Tree to call this method.
virtual void KrImNode::SetColor | ( | const KrColorTransform & | color, | |
int | window = KR_ALL_WINDOWS | |||
) | [virtual] |
Set the color of a node.
This color transforms all the node's children as well.
void KrImNode::SetNodeId | ( | int | id | ) |
Set the id of this node.
It must be > 0. This is completely user defined. Like the name, this should be unique. In DEBUG mode, an assertion will fire if an id is re-used.
You can later find a node by the id you set by calling KrImageTree::FindNodeById().
void KrImNode::SetNodeName | ( | const std::string & | name | ) |
Set the name of this node.
This is completely user defined. The name of a node should be unique. In DEBUG mode, an assertion will fire if the same name is used twice.
void KrImNode::SetPos | ( | int | x, | |
int | y, | |||
int | window = KR_ALL_WINDOWS | |||
) |
Set the x and y positon of the ImNode, relative to the node's parent.
Even non-drawing nodes have position since changing the position moves the node's children.
Setting the positon of the root node scrolls the screen.
void KrImNode::SetQuality | ( | int | quality, | |
int | window = KR_ALL_WINDOWS | |||
) |
Set the drawing quality for scaling.
Quality is inherited from the parent the same way other properties are, if the quality is set to KrQualityNone, else the set quality is used. Cached scaling is always at maximum quality.
virtual void KrImNode::SetVisible | ( | bool | visible, | |
int | window = KR_ALL_WINDOWS | |||
) | [virtual] |
If visible is set to false, this node and all its children will not show up on the stage.
Returns true if the visiblity was changed by this call.
virtual KrImNode* KrImNode::ToExtended | ( | const std::string & | type | ) | [inline, virtual] |
A generic cast.
The Kyra library is not as extensible as it could be; this implements a "cheap RTTI" if you add your own sub-classes. Arbitrary casting to any type in the string. For example,
MyClassType* myType = (MyClassType*) node->ToExtended( "MyClassType" );
Reimplemented in KrConsole.
int KrImNode::ZDepth | ( | ) | [inline] |
Every node has a Z-Depth within the node that contains it.
The lowest z-depth is the farthest from the viewer. Any integer value is acceptable.
Nodes at the same z-depth are sorted by the order they were added to the tree. The last one added is the closest to the viewer. (It is not a good idea to mix z-depth changing and "order sorting." Go with one or the other.
Changing the z-depth of the root is meaningless. (It has no siblings.)
