# README for tkstackrpms
Stackrpms extensions to Tcl/Tk for Python. These are small useful additions that might not be useful to anyone else.
## Upstream
This project's upstream is at <https://bgstack15.ddns.net/cgit/tkstackrpms/>
## Alternatives
None. Write your own small extensions.
## Reason for existence
Some features include:
* New widgets: Tooltip, Statusbar
* Extended widgets:
* Spinbox with mousewheel support
* Checkbox that calls function on Enter/Space/MouseButton1
* Entry that calls function on Enter/FocusOut
* Radiobutton that allows keyboard navigation through all related (by same variable) radiobuttons: Home, End, Up, Down.
* Poor-man's Gtk 3.0 icon name to path resolution
* Load image from svg
* Function `flash_entry` that cycles through a list of colors, at a provided duration per color. Useful for flashing an error.
My added value includes:
* The radiobutton keyboard navigation. To make that possible, I had to write a recursive function to find all related radiobuttons (that use the same variable) within this toplevel widget.
* A vastly improved flash_entry.
* The reimplementation of gtk 3.0 icon path resolution.
## Using
Ideally, this would be installable with pip3. But since I don't know how to do that, perhaps just copy [src/tkstackrpms/__init__.py](src/tkstackrpms/__init__.py) to your own project as `tkstackrpms.py`.
## Dependencies
For Devuan:
* python3-tk
* python3-pil.imagetk
* python3-cairosvg (OPTIONAL, for svg image support)
