Event Listener for a button in python extension

[ikks]

Hi, I’ve been working on a extension for libreoffice, using scriptforge, So far it has helped me to build things without taking too long to grok on documentation in different places.

I found something that I’m not understanding: How to bind an action to a button. From the docs it seems that I need to have a macro to be launched from the event.

onhelp = "service:org.fectp.StableHordeForLibreOffice?get_help"



        dlg = CreateScriptService(
            "NewDialog", "AIHordeOptionsDialog", (47, 10, 265, 206)
        )
        button_help = dlg.CreateButton("CommandButton1", (23, 15, 13, 10))
        button_help.Caption = "?"
        button_help.OnKeyPressed = onhelp # <a macro here> This reference does not work



class AiHordeForLibreOffice(unohelper.Base, XJobExecutor, XEventListener):
    """Service that creates images from text. The url to be invoked is:
    service:org.fectp.AIHordeForLibreOffice
    """

    def trigger(self, args):
        print(args)
        if args == "create_image":
            generate_image(self.desktop, self.context)
        if args == "validate_form":
            print("validate_event")
        if args == "get_help":
            print("get_help")




g_ImplementationHelper = unohelper.ImplementationHelper()
g_ImplementationHelper.addImplementation(
    AiHordeForLibreOffice,
    LIBREOFFICE_EXTENSION_ID,
    ("com.sun.star.task.JobExecutor",),
)

g_exportedScripts = (get_help,)

The problem is that I need to have a reference to the running process in order to let it be notified, and I was understanding that a macro is outside the context, and I don’t see how can I pass a reference to the macro. I’m not able either to publish a macro from my extension. in addition, I tried creating a function and using g_exportedScripts with no luck.

I haven’t found documentation on this particular purpose or a different way to bind an event without a macro to a control with scriptforge.

Basically What I’m doing is running a thread and I want to let the user cancel the thread pushing a button, but I haven’t managed to put a listener. and react inside the same extension.

The only option is to avoid scriptforge and rebuild the dialog? Or is there a choice with scriptforge that I’m maybe missing?

I have never used ScriptForge, but if you have a standard UNO object in this variable (button_help), then you just need to add the respective listener.

For example:

button_help.addMouseListener(EventsMouse())

You can see EventoMouse and other classes controllers at:

easymacro/source/pythonpath/easymacro/easyevents.py at master

Only like example:

import easymacro as app


class Events():

    def __init__(self, dialog):
        self.d = dialog

    def cmd_help_click(self, event):
        app.msgbox('Click')
        return


def main():

    opt = {
        'Title': 'AIHordeOptionsDialog',
        'Width': 100,
        'Height': 50,
    }
    dialog = app.dialog.create(opt)

    opt = {
        'Type': 'Button',
        'Name': 'cmd_help',
        'Label': '?',
        'Width': 50,
        'Height': 15,
        'X': 10,
        'Y': 10,
    }
    dialog.add_control(opt)

    dialog.events = Events
    dialog.open()

    return

You don’t have to use easymacro, just follow my source code to reproduce the event.
