QtVCP can be used to *create control panels* that interface with _HAL_.

[[sec:qtvcp:panels:builtin]]
== Builtin Virtual Control Panels

There are several *builtin HAL panels* available.

In a terminal type `qtvcp list` to see a list.

//TODO Add list output

[[sub:qtvcp:panels:copy]]
=== `copy`

Used for *copying QtVCP's builtin Screens/VCP Panels/QtVismach code to
a folder* so one can _customize_ it.

In a terminal run:

[[sub:qtvcp:panels:test-dial]]
=== `test_dial`

- This panel has a *dial that adjusts S32 and Float HAL output pins*.
- The dial's range can be adjusted from a drop down menu.
- The output can be scaled with the `spinbox`.
- A `combobox` can be used to automatically select and connect to a
  signal.

loadusr qtvcp test_dial

image::images/qtvcp_test_dial.png["QtVCP test_dial Panel - Test Dial VCP",align="center"]

=== test_button

- This panel has a *button that will set a HAL pin*.
- The button can be selected as a _momentary_ or a _toggle_ button.
- The button's _indicator color_ can be adjusted from a drop down menu.
- You can add more buttons from the drop down menu.
- You can load a Halmeter from the drop down menu.
- You can load a test LED from the drop down menu.
- The button can be detached from the main windows.

Here is how to load `test_button` from a HAL script:

[source,{hal}]
----
loadusr qtvcp test_button
loadusr qtvcp -o 4 test_button
----

The `-o` switch sets how many buttons the panel starts with. +
If loading directly from a terminal omit the `loadusr`.

[[sub:qtvcp:panels:test-led]]
=== `test_led`

- This panel has an *LED that can selected to watch HAL bit pins/signals*.
- The LED's color can be adjusted from a drop down menu.
- The text box and state can be output as speech if sound is selected.
- A `combobox` can be used to automatically select and connect to a
  pin/signal.
- You can add more LEDs from the drop down menu.
- The LED can be detached from the main windows.

Here is how to load `test_led` from a HAL script:

[source,{hal}]
----
loadusr qtvcp test_led
loadusr qtvcp -o 4 test_led
----

The `-o` switch sets how many LEDs the panel starts with. +
If loading directly from a terminal omit the 'loadusr'.

[[sub:qtvcp:panels:tool-dialog]]
=== `tool_dialog`

*Manual tool change dialog* that gives tool description.

[source,{hal}]
----
loadusr -Wn tool_dialog qtvcp -o speak_on -o audio_on tool_dialog
----

Options:

* `-o notify_on` - _use desktop notify_ dialogs instead of QtVCP native
  ones.
* `-o audio_on` - _play sound on tool change_
* `-o speak_on` - _speak announcement of tool change_

[[sub:qtvcp:panels:vismach]]
== `vismach` 3D Simulation Panels
These panels are prebuilt simulation of common machine types.

These are also embed-able in other screens such as AXIS or GMOCCAPY.

[[sec:qtvcp:panels:custom]]
== Custom Virtual Control Panels

You can of course *make your own panel and load it*.

If you made a UI file named `my_panel.ui` and a HAL file named
`my_panel.hal`, you would then load this from a terminal with:

----
halrun -I -f my_panel.hal
----

.Example HAL file loading a QtVCP panel
[source,{hal}]
----
# load realtime components
loadrt threads
loadrt classicladder_rt

# load user space programs
loadusr classicladder
loadusr -Wn my_panel qtvcp my_panel.ui  # <1>

# add components to thread
addf classicladder.0.refresh thread1


# connect pins
net bit-input1     test_panel.checkbox_1        classicladder.0.in-00
net bit-hide       test_panel.checkbox_4        classicladder.0.hide_gui

net bit-output1    test_panel.led_1             classicladder.0.out-00

net s32-in1        test_panel.doublescale_1-s   classicladder.0.s32in-00

# start thread
start
----

<1> In this case we load `qtvcp` using *`-Wn`* which waits for the panel
    to finish loading before continuing to run the next HAL command. +
    This is to _ensure that the panel created HAL pins are actually done_
    in case they are used in the rest of the file.
