No longer need a specialization for bool as PBD::to_string/string_to already
has specializations for bool
Remove template specialization for float as string_to/to_string handles string
representations of infinity
Since 5.8-245-g3e43585fa, a response hides the dialog Window
in ArdourDialog::on_response (to prevent dialogs windows staying
around unresponsive while Ardour does background work).
The RF is special, and also the only dialog using explicit
add_action_widget().
A Dialog Window may not be tightly scoped, and may be around
for a while (query settings from the dialog instance). The destructor
may only be called later.
This can be hard to reproduce and I have not been able to work out the steps to
reproduce reliably, but as it is still occuring work around the issue by just
checking the variable is valid before dereferencing it.
Resolves: #7304
Lua serialize() is called recursively and concatenates strings.
(in Lua that results in a new string on the stack, with 2 unused old
strings). Collecting garbage every time becomes expensive, so do it
only once at the end. GUI scripts are not memory limited anyway.
This reverts commit b3722f7063.
In some cases ardour shows context-menu on right-mouse-button
release. In this case selecting a menu-entry should happen
with the left-mouse button (or any button?!)
Using ev->button is only correct if the menu is temporary and only
visible while the button is held, button release then activates the
menu-item.
This needs further work, in some cases allowing any button (0) to work
makes sense and overall consistency needs to be improved.
Different places use different strategies for context-menus which
don't always match the button used in the event-handler.
This is a hotfix (to make TAV context menus work again with left-click)
This fixes an -Woverloaded-virtual ambiguity introduced in b5e613d45
void render (cairo_t*, cairo_rectagle*)
void render (Cairo::RefPtr<Cairo::Context> const&, cairo_rectangle_t*)
ArdourCanvas prefers cairomm and CairoWidget itself uses Cairo::Context,
this improves overall API consistency.
For reasons unknown[1], The vca-counter may not be in sync with
actual number of VCAs present.
[1] possibly some shared-ptr references at the time of session-save, or
old session compatibility.
