Module for managing images for scripting.
Images are identified by a string ID which is passed to ScreenImageMgr members when it is necessary to specify an image to work with. Member functions in this class which modify the state of the class are all mediated through the signal/slot mechanism to ensure such operations happen in the main thread where images are drawn, and not in the script thread.
Definition at line 103 of file ScreenImageMgr.hpp.
ScreenImageMgr::ScreenImageMgr | ( | ) |
Construct a LabelMgr object.
|
slot |
Create an image from a file and display on the screen at x,y coordinates.
id | the ID to use when referring to this image (an arbitrary string). |
filename | the partial path of the file to load. This will be searched for using StelFileMgr, with "scripts/" prefixed to the filename. |
x | The x-coordinate for the image (0 = left of screen) |
y | The y-coordinate for the image (0 = bottom of screen) |
scale | Image scale multiplier. |
visible | The initial visible state of the image |
alpha | The initial alpha (transparancy) value for the image (range 0.0 to 1.0) |
fadeDuration | the time it takes for screen images to fade in/out/change alpha in seconds. |
|
slot |
Delete all images currently managed by ScreenImageMgr.
|
slot |
Delete an image.
id | the ID for the desired image. |
|
virtual |
Execute all the drawing functions for this module.
core | the core to use for the drawing |
renderer | Renderer to draw with. |
Reimplemented from StelModule.
|
slot |
Get a list of currently loaded image IDs.
|
virtual |
Defines the order in which the various modules are drawn.
Reimplemented from StelModule.
|
slot |
Set an image's visible status.
id | the ID for the desired image. |
|
slot |
Find out if an image is currently visible.
id | the ID for the desired image. |
|
virtual |
Initialize itself.
If the initialization takes significant time, the progress should be displayed on the loading bar.
Implements StelModule.
|
slot |
Set an image's alpha value when visible.
id | the ID for the desired image. |
alpha | the new alpha value to set. |
|
slot |
Set the x and y coordinates for the specified image.
id | the ID for the desired image. |
x | The new x-coordinate for the image. |
y | The new y-coordinate for the image. |
duration | The time for the change to take place, in seconds. |
|
virtual |
Update time-dependent parts of the module.
