Getting user selected item from Listbox?

[willasm]

Is there any method of getting the users selection from a listbox? I have looked through the source in fpg_listbox.pas and there does not appear to be any function like GetSelectedItem or anything similar. I have tried using OnChange which works fine for the notification but it only sends the Sender TObject and not the the item index of the changed item. I have tried looping through all the items and I can get the text for each item but there also does not seem to be any method for getting the state of the item, selected or not.

Any suggestions would be appreciated, Thank you, William

You can use the FocusItem property for that.

Thanks for the info. I actually figured this out late last night after posting this question. Using FocusItem is much shorter than the method I figured out though.

procedure TMainForm.PropertiesOnChange(Sender: TObject);
var
  itemIndex1: Integer;
  itemIndex2: Integer;
  itemString: String;

begin
  itemIndex1 := lstProperties.FocusItem;
  itemIndex2 := lstProperties.Items.IndexOf(lstProperties.Text);
  itemString := Trim(lstProperties.Text);

  // Prints listbox item clicked index
  WriteLn(itemIndex1);
  WriteLn(itemIndex2);
  // Prints listbox item clicked string
  WriteLn(itemString);

end;

Also wanted to say I managed to get vscode setup for Free Pascal Compiler and with the help of the plugin FreePascal Toolkit it now has auto-completion for fpGUI which is awesome. I setup my tasks.json the way I want and I can now build debug/ release versions, run UIDesigner with the projects form, open fpgui.inf with search for keyword from the editors selected text and finally run the executable program. All of these have hotkeys assigned so having to use the menu is not necessary.

I started with Lazarus but 6gb really? It also corrupted my keyboards leds every time I compiled anything (never figured out why?) which required a reset to fix. Then I tried MSEIDE but documentation is very limited for it. It also has no Listbox in its widget set and I use Listboxes very often. Managed to imitate one with a string grid but it was far from ideal and yours just works and looks great.

Thanks, William

That's fantastic news, and glad you got a fully working environment now. I've never really used VSCode, but now I'm very curious. :-) Any setup tips or configs you can share for a complete first-timer like me?

On a side note:
I'm busy building a IDE, and taking a lot of design/functionality cues from IntelliJ for Java (what I use at work). So keyboard usage and extremely fast navigation to anything in the project is a must. Maximus (the IDE) is slowly getting there. I haven't gotten to the "make me look pretty" part yet, but the functionality is coming along - finishing up the OPDF debugger support, and then moving onto Git integration.

I would love if you could give it a try and give some feedback if you don't mind. It's a tool for developers, so I want to make sure I cater for others too - not just my own needs. Compile and open any project.xml file. I'm moving away from the traditional Delphi-style IDE, and "Project Settings" and "Compiler Settings" dialogs, to more auto-discovery and conventions-over-configurations, via the PasBuild build tool (also something I wrote).
