wxGUI vector and raster querying

[wenzeslaus]

The current state of map querying in wxGUI is not sufficient and some general solution (from user point of view) is needed.

Wider discussion is necessary but there are some known problems already.

Several inconsistencies and problems:

• different text formatting for vector and raster
• for vector map with db table dialog is displayed but for map without only v.what output is printed
• vector attribute dialog is editable
• coordinates are displayed only sometimes
• for vector map with some layers with db table and some without, only layers with are displayed

Highly related tickes:

• #251 Enhancements to vector querying
• #304 quering disables vector transparency
• #523 wxGUI: querying a vector map in edit mode does nothing
• #547 Raster query in wxGUI
• #951 Error querying rasters in wxgui
• #1402 Allow input coordinates to v.what to create a bounding rectangle for querying
• #1469 wxgui vector query doesn't work for maps without attribute table
• #1522 dbm_base.py fails with multilayer maps
• #1606 attribute query tool reports "nothing found" when clicking on a vector object
• #1607 attribute query fails to display text attribute values
• #1608 WXGUI attribute query might lead to accidental attribute data editing
• #1609 WXGUI doesn't offer a supported encodings for "Attribute data encoding" setting

Many of listed issues have been solved, still without significant overhaul of whole system :( Could this be a GSoC task?

Another related issue: #1824

Recently reimplemented in trunk. Anything left?, could we closed this ticket?

Replying to martinl:

From me, everything is fulfilled. Only the last point was not tested (for vector map with some layers with db table and some without, only layers with db table are displayed). But this may be caused by v.what behavior.

For further reference, here is the list of still open related tickets:

• #251 Enhancements to vector querying
• #304 quering disables vector transparency
• #523 wxGUI: querying a vector map in edit mode does nothing
• #1402 Allow input coordinates to v.what to create a bounding rectangle for querying
• #1824 wxGUI should offer a vector geometry query tool
• #1826 New d.mon doesn't allow querying (can be closed soon)
