# CHANGELOG
## v0.74.1 (2024-06-26)
## v1.7.0 (2024-12-02)
### Build
### Bug Fixes
* build: added missing pytest-bec-e2e dependency; closes #219 ([`56fdae4`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/56fdae42757bdb9fa301c1e425a77e98b6eaf92b))
- **tests**: Add test for Console widget
([`da579b6`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/da579b6d213bcdf28c40c1a9e4e2535fdde824fb))
* build: fixed dependency ranges; closes #135 ([`e6a06c9`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/e6a06c9f43e0ad6bbfcfa550a2f580d2a27aff66))
### Features
### Chore
- **console**: Add "prompt" signal to inform when shell is at prompt
([`3aeb0b6`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/3aeb0b66fbeb03d3d0ee60e108cc6b98fd9aa9b9))
- **console**: Add 'terminate' and 'send_ctrl_c' methods to Console
([`02086ae`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/02086aeae09233ec4e6ccc0e6a17f2b078d500b8))
.terminate() ends the started process, sending SIGTERM signal. If process is not dead after optional
timeout, SIGKILL is sent. .send_ctrl_c() sends SIGINT to the child process, and waits for prompt
until optional timeout is reached. Timeouts raise 'TimeoutError' exception.
## v1.6.0 (2024-11-27)
### Bug Fixes
- Add back accidentally removed variables
([`e998352`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/e9983521ed2a1c04af048a55ece70a1943a84313))
- Differentiate click and drag for DeviceItem, adapt tests accordingly
([`cffcdf2`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/cffcdf292363249bcc7efa9d130431d0bc727fda))
This fixes the blocking "QDrag.exec_()" on Linux, indeed before the drag'n'drop operation was
started with a simple click and it was waiting for drop forever. Now there are 2 different cases,
click or drag'n'drop - the drag'n'drop test actually moves the mouse and releases the button.
- Do not quit automatically when last window is "closed"
([`96e255e`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/96e255e4ef394eb79006a66d13e06775ae235667))
Qt confuses closed and hidden
- No need to call inspect.signature - it can fail on methods coming from C (like Qt methods)
([`6029246`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/60292465e9e52d3248ae681c68c07298b9b3ce14))
- **rpc**: Gui hide/show also hide/show all floating docks
([`c27d058`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/c27d058b01fe604eccec76454e39360122e48515))

([`2fe7f5e`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/2fe7f5e1510a5ea72676045e6ea3485e6b11c220))
- **tests**: Make use of BECDockArea with client mixin to start server and use it in tests
([`da18c2c`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/da18c2ceecf9aeaf0e0ea9b78f4c867b27b9c314))
Depending on the test, auto-updates are enabled or not.
### Features
- '._auto_updates_enabled' attribute can be used to activate auto updates installation in
BECDockArea
([`31d8703`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/31d87036c9801e639a7ca6fc003c90e0c4edb19d))

- Add rpc_id member to client objects
([`3ba0b1d`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/3ba0b1daf5b83da840e90fbbc063ed7b86ebe99b))
- Asynchronous .start() for GUI
([`2047e48`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/2047e484d5a4b2f5ea494a1e49035b35b1bbde35))
- Do not take focus when GUI is loaded
([`1f71d8e`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/1f71d8e5eded9952f9b34bfc427e2ff44cf5fc18))
- **client**: Add show()/hide() methods to "gui" object
([`e68e2b5`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/e68e2b5978339475b97555c3e20795807932fbc9))
- **server**: Add main window, with proper gui_id derived from given id

## v1.5.1 (2024-11-14)
### Bug Fixes
- **plugin_utils**: Plugin utils are able to detect classes for plugin creation based on class
attribute rather than if it is top level widget
([`7a1b874`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/7a1b8748a433f854671ac95f2eaf4604e6b8df20))

Launcher for BEC GUI Applications
