Control multiple machines with one gui

mrjj

But how do you connect or talk to machine?

javcursor

We send the command to other "pc" that interact with machines using MODBUS-TCP. The commands of buttons have the same function but they have to act over different devices. For example I have eight move buttons, all of them have the same function (send the command move) but each one send the command to a different device.

PD: sorry if my english is not good but it is not my maternal language

@javcursor
Your english is fine. :) most of us are not native English either.

Ok. via TCP.

So why cannot you not have a a machine selector. Like Combobox
where u select machine. ?

And then the move buttons will send to that machine.
If u choose no 2 machine, it sends to that one. etc.

It would be strange design to have 8 Move buttons. Unless there is
good reason , i completely missed :)

@mrjj

One reason could be that you want send the same command to multiple machines at the same time.
Maybe a ListView with multiselect would be a slightly better solution.

mrjj

@the_

Indeed. In such case a list will be better. :)

But having 8 move buttons
would still not really be at same time as there would be delay
moving mouse between them and clicking.

But Im just guessing. Not sure what his requirements are. :)

javcursor

Imagine this GUI (image hear). I can have an Id for each machine but in that case I need a switch/if...else to select the correct objective.

I want know if it is posible only do the GUI for machine1, then do a complete gui with multiple elements of type GUI for machine1 and manage those elements with some class/function of high level of Qt.

@javcursor
hi
Are you asking if its possible to just have one GUI instead of many of the same
and then just select machine or
what is the real question?

I dont understand the last part.

"if it is posible only do the GUI for machine1, then do a complete gui with multiple elements of type GUI for machine1"

But most likely the answer is yes :)

So when you press button it will call
DoMoveCommand( SelectedMachine, xxx)

Hi! In Qt Creator, in your project, select "Add new...", then "Qt Designer Form Class" and then choose "Widget" as a form template. You can now build a widget containing all the buttons and stuff to control a single machine. This widget is reusable, this means you can add as many instances of it to your main window as you like.

Ok, that is the idea. I'll try build a widget.

Thank you all.

mrjj

so you want 8 times the same GUI?
Not 1 GUI and u select machine?

javcursor

Yes, it is a requisite

mrjj

@javcursor
Ok, then a widget is best approach.
And then create 8 instances in the mainwindow.
