# BlitzTUI Mini-Tutorial
|
||
|
|
|
||
|
|
This *Mini-Tutorial* shows the basic workflow for doing changes to the Blitz-Touch-User-Interface.
|
||
|
|
|
||
|
|
## What you need
|
||
|
|
|
||
|
|
* A physical RaspiBlitz and SSH access to it (to verify your changes on the real screen)
|
||
|
|
* A Computer (Mac and Windows should work)
|
||
|
|
* The "Qt Designer" software (https://build-system.fman.io/qt-designer-download)
|
||
|
|
* A copy of the current RaspiBlitz codebase (`git clone https://github.com/rootzoll/raspiblitz.git`)
|
||
|
|
|
||
|
|
## Scenario
|
||
|
|
|
||
|
|
Let's assume you want to reduce the width of the button row on the left side.
|
||
|
|
|
||
|
|
* Open Qt Designer
|
||
|
|
* Load the .ui file: `home.admin/BlitzTUI/designer/home.ui`
|
||
|
|
|
||
|
|
Your screen should look similar to this:
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
* (1) for this scenario go to the **Object Inspector** and select **splitter**
|
||
|
|
* (2) change the **Width** (e.g. from 80 to 60)
|
||
|
|
* (3) this should be reflected in the preview Window
|
||
|
|
* (4) save your changes
|
||
|
|
|
||
|
|
The next step is to transfer (use scp or WinSCP) the updated `home.ui` to the RaspiBlitz.
|
||
|
|
|
||
|
|
Login to your RaspiBlitz as **admin** (Password A) and change the directory to `~/raspiblitz/home.admin/BlitzTUI`.
|
||
|
|
|
||
|
|
Your updated `home.ui` file should be in `designer/` (confirm timestamp with `ls -l designer/home.ui`).
|
||
|
|
|
||
|
|
Run `make build-ui`
|
||
|
|
|
||
|
|
To quickly check the result run
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo -u pi DISPLAY=:0.0 LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1.2.0 /home/admin/python3-env-lnd/bin/python3 /home/admin/raspiblitz/home.admin/BlitzTUI/blitztui/main.py
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also install the current directory as a python package using `pip install -e .` and the run
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo -u pi DISPLAY=:0.0 LD_PRELOAD=/usr/lib/arm-linux-gnueabihf/libatomic.so.1.2.0 /home/admin/python3-env-lnd/bin/blitz-tui
|
||
|
|
```
