Module gwy :: Class LayerBasic |
|
LayerBasic The ::presentation-switched signal is emitted when the presentation state changes, that is when a layer which displayed data directly starts displaying a presentation, or conversely when it stops displaying a presentation.
('gwydataview', ' The #GwyLayerBasic which received the signal. ')Method Summary | |
---|---|
Creates a new basic data displaying layer. | |
Gets key identifying color gradient. | |
Tests whether a basic layer displays a presentation instead of the data. | |
Gets prefix identifying fixed range minimum and maximum. | |
Gets the key identifying data field this pixmap layer actually displays. | |
Gets the range colors are mapped from in current mode. | |
Gets the current color mapping mode. | |
Gets key identifying color range mapping type. | |
Sets the container key of the colour gradient to use to visualize data. | |
Sets basic layer fixed range minimum and maximum. | |
Sets the container key of the data field to actually display by a basic layer. | |
Sets the container key of the color range mapping type to use to visualize data. |
Method Details |
---|
__init__()
Creates a new basic data displaying layer.
|
get_gradient_key()Gets key identifying color gradient.
|
get_has_presentation()Tests whether a basic layer displays a presentation instead of the data.
|
get_min_max_key()Gets prefix identifying fixed range minimum and maximum.
|
get_presentation_key()Gets the key identifying data field this pixmap layer actually displays. SeeLayerBasic.set_presentation_key () for
details.
|
get_range(min, max)Gets the range colors are mapped from in current mode. This function does not take presentations into account. It always returns ther range corresponding to the underlying data even if a presentation is shown instead.
|
get_range_type()Gets the current color mapping mode.
|
get_range_type_key()Gets key identifying color range mapping type.
|
set_gradient_key(key)Sets the container key of the colour gradient to use to visualize data.
|
set_min_max_key(prefix)Sets basic layer fixed range minimum and maximum.
|
set_presentation_key(key)Sets the container key of the data field to actually display by a basic layer. The data field set withPixmapLayer.get_data_key () is used to
obtain values, it determines physical dimensions, etc. When a data
field is set with this method, it is displayed instead of the actual
data.
|
set_range_type_key(key)Sets the container key of the color range mapping type to use to visualize data.
