Add functionality to open the containing folder of a file that's selected
in LMMS' file browser.
Technical details
------------------
Add a new private method openContainingFolder to FileBrowser. Add a new
action to the context menu of a selected file. This action in turn calls
the added method.
The current implementation of openContainingFolder delegates to
QDesktopServices::openUrl with the directory of the selected file. Please
note that this will only open the directory but not select the file as
this is much more complicated due to different implementations that are
needed for the different platforms (Linux/Windows/MacOS).
Using QDesktopServices::openUrl seems to be the most simple cross
platform way which uses functionality that's already available in Qt.
* Move m_key member of Effect into Plugin
* Pass key to Instrument ctors and instantiaters
* Add pluginKeys to all plugin selector widgets, and let them pass the keys
when instantiating the instruments; or, if the keys must be passed over
threads, pass the keys to the Engine using `Engine::setDndPluginKey()`
* As instrument plugin libraries now also need to get their key passed, their
second argument, which was always the same as the first, is now used to pass
the sub plugin keys. This affects *all* instrument plugins.
* Plugin.h: Add more virtuals to `SubPluginFeatures` in order to draw logos
and images into instrument selector widgets
* LadspaSubPluginFeatures: Implement the `displayName` virtual because the
new behaviour to resolve displayNames is to first look at the
SubPluginFeatures, which, without override, returns the superior plugin's
name (Plugin.cpp)
Additional:
* PluginFactory.h: Allow setting up search paths without discovering plugins
yet
* Plugin.h: Add full documentation (should be checked)
Moving empty destructors out of the .cpp files and into headers
allows them to be devirtualized in certain cases.
(When the compiler can't "see" a function in a header, it must largely
assume it's some black box that the linker will resolve.)
While we're at it, use C++11's `= default` to define empty virtual
desturctors for us.
For some classes (e.g., Piano), nothing is derived from it, so we can
mark the class as final and remove any explicit virtual dtor.
There are many other places where this can be done, but this is a large
enough patch as-is.
Move the search bar on top of the file browser for the following sidebar
windows:
* "My Projects"
* "My Samples"
* "My Presets"
* "My Home"
* "My Computer"
Add the greyed out text "Search" to the search text edit.
The text is only shown as long as no text is entered in the search field.
Also rename some variable names to something more meaningful. Rename the
member m_l of FileBrowser to m_fileBrowserTreeWidget. Rename the
following local variables in the constructor of FileBrowser:
* ops -> searchWidget
* opl -> searchWidgetLayout
Removes one of the several calls to pointSizeF. This method seems to
return a font which has the same height in pixels on all displays
(regardless of the display's actual DPI value). In the long run these
calls will all have to be removed to make LMMS usable on high DPI
displays.
Removed trying to validate non lmms files when clicked in the file browser.
This had been the cause of erronus dialog box, and caused a bug, not allowing
drag and drop of sf2 files.
