This turns `IdleRegister::add()` into a template function to make the
provided function pointers type safe. It also adds a `delete_data`
parameter to manage the provided data pointer even in `destroy()`.
- Curve editor buttons are set to expand by default, but they are set to
shrink as soon as an accompagnying widget is set to expand
- White Balance's method button now has a centered ellipse ("...")
- White Balance's buttons are now aligned on their right
- A "withScrollbar" class is added to MyExpander if the ToolPanel's
vertical scrollbar is visible. This can let you add padding space for
the scrollbar (see #MyExpander.withScrollbar in RT default theme)
- A "maximized" and "fullscreen" class is added to the RTWindow whenever
it change state ; BEWARE: if you maximize the window then make it
fullscreen, Gtk says that the window is in a "maximized & fullscreen"
state, which mean that both class can be added at the same time to the
window.
One Gtk oddity (at least on Windows) is that you can make your window
fullscreen and still drag it around by its header bar... That's not very
practical to click on the unfullscreen button if in Single Editor mode
with vertical Tab.
I also managed to see the window in a Inconified + Maximized state. This
part of Gtk doesn't seem very robust, on Windows at least.
This commit include :
- cleanup rtgui/retinex.cc file (constructor only) and switched to
Gtk::Grid (the new standard) instead of Gtk::Box. This however doesn't
solve the issue of the Transmission curves in the Retinex tool, with
wrong resize of the Frame when folding/unfolding the curves.
- better alignment of the Histogram panel now with 4px of padding on the
left and right side
- Threshold selector now use the Scale's Trough style to draw its box
and sliders
- Curve's background are darker and restricted to the curve diagram
- Diagonal and Flat curves has been converted to Gtk::Grid as well
- A special color is now used for unsensitive Threshold selector and
Sclaes widgets
- Gap around the main Window has been removed on windows to circumvent a
bug in Gtk3, but the window can now only be maximized (usual use case)
or resized vertically by the top border only.
- Buttons at the bottom of the Editor panel has now the same height
- Fix the Histogram background and grid lines
- Add 1 pixel of empty space between in the Histogram panel
- Add a light grey color border for Gtk::DrawingArea oject, for those
using the render_frame method
- In the Toolbox, make the nested MyExpander and Gtk::Frame lighter, and
adjust the Gtk::DrawingArea background color accordingly
- All added class to the MyCurve has been removed, so that the
Gtk::Drawing object's style is used
- The Retinex Settings' expander is now level 2 for GUI consistency
