Reload SVG Symbology Directory

[otternase]

Environment: qgis 0.9.1 Ubuntu 7.10

Problem:

Qgis is loading the catalogue of available SVGs for symbology only on startup, so if after starting Qgis a new SVG is created or a SVG is deleted, the catalogue is not updated accordingly and the new SVG is not available in the Symbologydialog. As my plugin is creating new SVGs on runtime, which I want to be available in the Dialog, I tried this:

Suggestion: I changed qgsmarkercatalogue.cpp like this:

Now every time my plugin is constructing a new SVG, I call the updateMarkerCatalogue() like this

---

QgsMarkerCatalogue *markerCatalogue=QgsMarkerCatalogue::instance(); markerCatalogue->updateMarkerCatalogue();

---

Tested in above named environment and it worked fine.

If this change is accepted there would probably even be the opportunity to do this MarkerCatalogue Update every time the Symbology Dialog is opened automatically???

What is your plugin? Is it available somewhere?

hi,

a) is the plugin available somewhere?

b) has this patch already been evaluated/committed by the devs?
