# CHANGELOG
## v0.103.0 (2024-09-04)
## v1.7.0 (2024-12-02)
### Ci
### Bug Fixes
* ci: prefill variables for manual pipeline start ([`158c19e`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/158c19eda771562a325fd59405f9fd4cb9a17ed6))
- **tests**: Add test for Console widget
([`da579b6`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/da579b6d213bcdf28c40c1a9e4e2535fdde824fb))
### Feature
### Features
* feat(vscode): open vscode on a free port ([`52da835`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/52da835803f2453096a8b7df23bee5fdf93ae2bb))
- **console**: Add "prompt" signal to inform when shell is at prompt
([`3aeb0b6`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/3aeb0b66fbeb03d3d0ee60e108cc6b98fd9aa9b9))
* feat(website): added method to wait until the webpage is loaded ([`9be19d4`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/9be19d4abebad08c5fc6bea936dd97475fe8f628))
- **console**: Add 'terminate' and 'send_ctrl_c' methods to Console
([`02086ae`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/02086aeae09233ec4e6ccc0e6a17f2b078d500b8))
### Fix
.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.
* fix(theme): fixed segfault for webengineview for auto updates ([`9866075`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/9866075100577948755b563dc7b7dc4cdc60d040))
### Test
## v1.6.0 (2024-11-27)
* test(webview): fixed tests after refactoring ([`d5eb30c`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/d5eb30cd7df4cb0dc3275dd362768afc211eaf2d))
### Bug Fixes
* test(vscode): popen call does not have to be the only one ([`39f98ec`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/39f98ec223ba8b59e478ac788c08c59ffe886b4e))
- 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))
- **server**: Use dock area by default
([`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))

- 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

attribute rather than if it is top level widget
([`7a1b874`](https://gitlab.psi.ch/bec/bec_widgets/-/commit/7a1b8748a433f854671ac95f2eaf4604e6b8df20))

Unblocking the proxy needs to be done through the slot unblock_proxy. The most likely use case for this class is
when the callback function is potentially initiating a slower progress, i.e. requesting a data analysis routine to
analyse data. Requesting a new fit may lead to request piling up and an overall slow done of performance. This proxy
will allow you to decide by yourself when to unblock and execute the callback again."""

This module provides a utility class for counting and reporting frames per second (FPS) in a PyQtGraph application.
Classes:
FPSCounter: A class that monitors the paint events of a `ViewBox` to calculate and emit FPS values.

The `FPSCounter` class can be used to monitor the rendering performance of a `ViewBox` in a PyQtGraph application.
