Save Plugin Button State

BlitzCoder

It would be nice to preserve the session or state of a button, if a plugin has a tool button placed on the menu.

Ideally where you always open notepad++ and the word wrap or indent guide are still on the same state where you left it off last.

Plugins can persist the state of docked panels with the NPPM_DMMREGASDCKDLG API (available since Notepad++ 4.0, according to the documentation).

It isn’t obvious to a non-technical user, but it’s really the plugin’s job to call the API. The editor just handles the call by saving the panel’s coordinates and visibility to %AppData%\config.xml, as illustrated in my post to the original thread.

It wouldn’t be practical for N++ to automatically register every loaded plugin like this. To begin with, not every plugin provides a panel. The ones that do provide them are responsible for marshalling their own data. The so-called “button state” of a docked panel is exactly what the tTbData structure is designed to serialize: the state of the T[ool] b[ar] where the plugin puts its icon.

Basically, what you’re asking for is already a long-standing feature. If a certain plugin is not using it (or using it wrongly), that’s an issue for the plugin’s maintainer to resolve.

The bug report is here, finally: https://github.com/nea/MarkdownViewerPlusPlus/issues/159

In the meantime, just putting .dll after the plugin name will get it working, e.g.,

<!-- <GUIConfig name="DockingManager" ... > -->
    <PluginDlg pluginName="MarkdownViewer++.dll" id="0" curr="1" prev="-1" isVisible="yes" />
<!-- </GUIConfig> -->
