# GUI

## Launch

In `prod`:
`ssh sls-vserv-bd-hla01`
```
cd /sls/bd/hla/prod/qt
../bin/sls_hla_launch_gui.sh A_BD_ServiceManager.ui
```

In `dev`:
`ssh sls-vserv-bd-hla01-dev`
```
cd /sls/bd/hla/dev/qt
../bin/sls_hla_launch_gui.sh A_BD_ServiceManager.ui "dev"
```

Any extra arguments are passed straight through to `caqtdm`, e.g. to set a macro:

```
../bin/sls_hla_launch_gui.sh A_BD_ServiceManager.ui "dev" -macro "OTHER_ENV_VAR=HEYHEY"
```

**Note:** launching straight from a git checkout, as above, uses the raw `.ui` files as
committed - including the literal `{{ agebd_env_suffix_upper }}`/`{{ agebd_env_suffix_lower }}`
placeholders in their PV names. Those only get substituted with `-DEV`/`-dev` (or emptied out,
in `prod`) at deploy time, by `.gitea/workflows/deploy.yml`'s `"Qt - deploy"` step, on the
*deployed* copy at `/sls/bd/hla/<env>/qt/`. If widgets show up blank or unresponsive, check
whether you're accidentally pointing at the raw checkout instead of the deployed `.ui` file.
