|
* Thuban/Model/layer.py (Layer.GetProjection): New. Needed to |
| 4 |
|
implement the interface that the ProjFrame dialog expects. |
| 5 |
|
|
| 6 |
|
* Thuban/Model/proj.py (Projection.SetName): New. Allows the |
| 7 |
|
name of the projection to be changed. |
| 8 |
|
(ProjFile): Use a dictionary instead of a list so that removing |
| 9 |
|
projections is easier and we are sure about uniqueness. |
| 10 |
|
(ProjFile.Remove): Remove the given projection object. |
| 11 |
|
|
| 12 |
|
* Thuban/Model/resource.py (GetSystemProjFiles, GetUserProjFiles): |
| 13 |
|
Return a list with only one projection file instead of searching for |
| 14 |
|
any projection file. This simplifies many things if the user can |
| 15 |
|
only have one system file and one user file. |
| 16 |
|
|
| 17 |
|
* Thuban/UI/classgen.py: Change all references to |
| 18 |
|
genCombo to genChoice. |
| 19 |
|
|
| 20 |
|
* Thuban/UI/mainwindow.py: Add a Projection option under the |
| 21 |
|
layer menu. |
| 22 |
|
(MainWindow.LayerProjection): New. Open up a projection window |
| 23 |
|
for a layer. |
| 24 |
|
|
| 25 |
|
* Thuban/UI/projdialog.py: Large changes to how the dialog is |
| 26 |
|
laid out. Use three panels instead of one. One for the list of |
| 27 |
|
projections, one for the edit controls, and one for the buttons. |
| 28 |
|
Fixed resizing problems so that the dialog resizes correctly |
| 29 |
|
when the projection panel changes. Added import/export, save, and |
| 30 |
|
new buttons/functionality. |
| 31 |

|
|
| 34 |
|
First step towards table management. Introduce a simple data |
| 35 |
|
abstraction so that we replace the data a layer uses more easily |
| 36 |
|
in the next step. |
| 37 |
|
|
| 38 |
|
* Thuban/Model/data.py: New file with a simple data abstraction |
| 39 |
|
that bundles shapefile and dbffile into one object. |

|
|
| 41 |
|
* Thuban/Model/session.py (Session.OpenShapefile): New method to |
| 42 |
|
open shapefiles and return a shape store object |
| 43 |
|
|
| 44 |
|
* Thuban/Model/layer.py (Layer.__init__): Pass the data as a store |
| 45 |
|
object instead of a shapefile filename. This introduces a new |
| 46 |
|
instance variable store holding the datastore. For intermediate |
| 47 |
|
backwards compatibility keep the old instance variables. |
| 48 |
|
(open_shapefile): Removed. No longer needed with the shape store. |
| 49 |
|
(Layer.SetShapeStore, Layer.ShapeStore): New methods to set and |
| 50 |
|
get the shape store used by a layer. |
| 51 |
|
(Layer.Destroy): No need to explicitly destroy the shapefile or |
| 52 |
|
table anymore. |
| 53 |
|
|
| 54 |
|
* Thuban/UI/mainwindow.py (MainWindow.AddLayer) |
| 55 |
|
(MainWindow.AddLayer): Use the session's OpenShapefile method to |
| 56 |

| 59 |
|
session's OpenShapefile method to open shapefiles |
| 60 |
|
|
| 61 |
|
* test/test_classification.py |
| 62 |
|
(TestClassification.test_classification): Use the session's |
| 63 |
|
OpenShapefile method to open shapefiles and build the filename in |
| 64 |
|
a more platform independed way |
| 65 |
|
|
| 66 |
|

| 70 |
|
session's OpenShapefile method to open shapefiles |
| 71 |
|
(TestLayerLegend.setUp): Instantiate a session so that we can use |
| 72 |
|
it to open shapefiles. |
| 73 |
|
(TestLayerLegend.tearDown): Make sure that all references to |
| 74 |
|
layers and session are removed otherwise we may get a resource |
| 75 |
|
leak |
| 76 |
|
|
| 77 |
|
* test/test_map.py (TestMapAddLayer.test_add_layer) |
| 78 |
|
(TestMapWithContents.setUp): Instantiate a session so that we can |
| 79 |
|
use it to open shapefiles. |
| 80 |

| 81 |
|
layers, maps and sessions are removed otherwise we may get a |
| 82 |
|
resource leak |
| 83 |
|
("__main__"): use support.run_tests() so that more info about |
| 84 |
|
uncollected garbage is printed |
| 85 |
|
|
| 86 |
|
* test/test_save.py (SaveSessionTest.testSingleLayer): Use the |
| 87 |
|
session's OpenShapefile method to open shapefiles |
| 88 |
|
("__main__"): use support.run_tests() so that more info about |
| 89 |
|
uncollected garbage is printed |
| 90 |
|
|
| 91 |
|
* test/test_selection.py (TestSelection.tearDown): Make sure that |
| 92 |
|
all references to the session and the selection are removed |
| 93 |
|
otherwise we may get a resource leak |
| 94 |
|
(TestSelection.get_layer): Instantiate a session so that we can |
| 95 |
|
use it to open shapefiles. |
| 96 |
|
("__main__"): use support.run_tests() so that more info about |
| 97 |
|
uncollected garbage is printed |
| 98 |
|
|
| 99 |
|
* test/test_session.py (TestSessionBase.tearDown) |
| 100 |
|
(TestSessionWithContent.tearDown): Make sure that all references |
| 101 |
|
to the session and layers are removed otherwise we may get a |
| 102 |
|
resource leak |
| 103 |
|

| 104 |
|
method to open shapefiles |

|
| 108 |
|
* Thuban/Model/load.py (XMLReader.read): Should have been checking |

If any of the proj files can't be read skip that file and go |
| 118 |
|
on to the next one. |
| 119 |
|
|
| 120 |
|
* test/test_proj.py: Added test cases to handle nonexistent files, |
| 121 |
|
unreadable files, and files that don't parse correctly. |
| 122 |
|
|
| 123 |
|

|
|
| 137 |
|
