QUESTION
I'm trying to create a model that can be used for both a QTableView and QTreeView. As an example, my data is something like:
ID Location Name 101 201 Apple 201 None Kitchen 102 201 Banana 301 None Cellar 302 301 Potatoes 202 302 NailSo every entry has a location which is itself an entry in the model. For the QTableView, I'd like to simply display all entries under each other as shown above, while for the QTreeView I'd like something like
- 201: Kitchen
- 101: Apple
- 102: Banana
- 301: Cellar
- 302: Potatoes
- 202: Nail
- 302: Potatoes
My problem however is that I can't figure out how to implement QAbstractProxyModel.maptoSource() or mapfromSource() as I lose information about the parent in the QTableView. Reading https://www.qtcentre.org/threads/26163-Map-table-to-tree-through-model-view-possible it seems that perhaps this is not possible at all. However the QAbstractProxyModel explicitly says that's it's meant for showing data in both views. Can anyone point me in the right direction or knows whether it's possible to implement a model like this? Especially in Python, I can't find any examples unfortunately.
I really like the idea of just using an unindented TreeView as a sort of TableView. Unfortunately I'm still having trouble creating the model. Currently, only the top entries are being shown.

Answered 2021-Feb-26 at 13:55As there is a distinct lack of examples for python, I'll post my modified version of the simpletreemodel here, which is what ended up working for me. By then using a QTreeView instead of a QTableView as suggested, I got the table to behave as I wanted it too. Overall, this creates MyItem which is an item containing the entire row of information and I then use recursion to add children to parents if their value for the hierarchy_key (location_id) is equal to the id of the parent.
QUESTION
I am trying to understand the anatomy of a font file, and wondering about how glyphs are mapped to keyboard characters.
As part of that, I am also wondering what you do when you have font glyphs that are not part of unicode, such as with FontAwesome icons. FontAwesome uses them in CSS like this:

Answered 2018-Sep-18 at 19:36A sane icon font offers GSUB ligature substitution, so that if your text contains a sequence of codepoints (like those associated with c + a + r
) the font does a remapping to an internal glyph (like the car icon) so while typing, you see this:

I have been working with Leaflet and Tabletop.js. The main idea is put all the data in Google Spreadsheet and use Tabletop for reading that data and then show on Leaflet. Almost works fine, except for one issue: If the points are very closer (like 2 meters) I can't see two points, only the last one. There is some configuration for that?
When I created the map, i use this code:
