Classes | |
struct | StelTextureParams |
Contains the parameters defining how a texture is created. More... |
For creating an instance, use StelTextureMgr::createTexture() and StelTextureMgr::createTextureThread()
virtual StelTexture::~StelTexture | ( | ) | [virtual] |
Destructor.
bool StelTexture::bind | ( | ) |
Bind the texture so that it can be used for openGL drawing (calls glBindTexture).
If the texture is lazyly loaded, this starts the loading and return false immediately.
bool StelTexture::canBind | ( | ) | const [inline] |
Return whether the texture can be binded, i.e. it is fully loaded.
bool StelTexture::getDimensions | ( | int & | width, | |
int & | height | |||
) |
Return the width and heigth of the texture in pixels.
const QString& StelTexture::getErrorMessage | ( | ) | const [inline] |
Get the error message which caused the texture loading to fail.
const QString& StelTexture::getFullPath | ( | ) | const [inline] |
Return the full path to the image file.
If the texture was downloaded from a remote location, this function return the full URL.
bool StelTexture::isLoading | ( | ) | const [inline] |
Return whether the image is currently being loaded.
bool StelTexture::glLoad | ( | ) |
Load the texture already in the RAM to the openGL memory This function uses openGL routines and must be called in the main thread.
void StelTexture::loadingProcessFinished | ( | bool | error | ) | [signal] |
Emitted when the texture is ready to be bind(), i.e.
when downloaded, imageLoading and glLoading is over or when an error occured and the texture will never be available In case of error, you can query what the problem was by calling getErrorMessage()
error | is equal to true if an error occured while loading the texture |
