two questions on my first plugin

Mario Rosenbohm

Hello,

i now programing on my first npp plugin (in C#) and i have any little questions ;-)

a) Is there exist an event or an message when the user change to another document?
b) Is exist an example or dev-guide for using localization?

Thats all for the begin.

I’m only able to tell you something about your question a)

There is a notification called NPPM_BUFFERACTIVATED (see here (slightly outdated) and here (up to date)). It is send to a plugin whenever a document’s text buffer (i.e. its tab) gets activated.

I’m a plugin author too (see here) thus I know that there are some pitfalls with NPPM_BUFFERACTIVATED. Activating a buffer often happens even in situations where you do not expect it.

Especially if your plugin does something with a text buffer which has to be done only one times you need to implement some sort of buffer management to remember that a certain buffer already has undergone your manipulations.

I personally ended up with a dictionary: The keys are buffer IDs and the values are the full paths of the related files. I solved it this way because it can happen that an already closed buffer ID gets reused by another file.

Hello dinkumoil,

thanks for suggestion, it is exactly what i search.

For all other C#-developers:

In file Main.cs write a new function with header “internal static void bufferIsActivated()”
this function is called by eventmanager on 2.
In file PluginInfrastructure/UnmanagedExports.cs in the function “static void beNotified(IntPtr notifyCode)” add follow code above the else statement:
```
     else if (notification.Header.Code == (uint)NppMsg.NPPN_BUFFERACTIVATED)
     {
         Main.bufferIsActivated();
     }
```

And now is calling your “bufferIsActivated”-function by change / activate a other tab.

thanks and regards
Mario

Hello everyone,

“see the forest for the trees” 8-)

in file PluginInfrastructure/UnmanagedExports.cs in the function “static void beNotified(IntPtr notifyCode)” in the else statement

        else
        {
            Main.OnNotification(notification);
        }

… Main.OnNotification(notification); … oh no
That is an callback. I am so stup…

have a nice day
Mario
