Prior to this change, a GUI layout was only affected by the screen size.
Now, a layout can additionally be influenced by the GUI dialog and widgets
that uses it. This capability is leveraged to implement the following
features:
* Layout elements that are not bound to a GUI widget do not take space.
This means that dialogs where the widgets shown depend on for example
a feature being enabled at configure time no longer have blank spaces.
* Widgets can define a minimal required size for their contents not to be
cut. For now this is only used for buttons so their width is always
sufficient for their caption not to be cut. This mechanism could be
applied to other widget types in the future.
DropdownButtonWidget is a button split in two parts vertically. Clicking
the left part triggers a default action. Clicking the right part shows a
list of other actions the user can choose from.
Using this widget on the launcher lets 'Mass add' be a secondary action
of the 'Add' button, removing the necessity of pressing the shift key to
access the feature.
Well, it ain't a fix, because it's not exactly correct for any of the
themes. Yet it's the best for all of them. If I put what seems to be
correct, "modern" theme gets ruined, because it has this mystical 2px
offset in tabs/scrollcontainers.
- removed +1px in ListWidget, added in lordhoto's 2007 commit 68eb28a
(aka r29971 in svn) `Fix for bug #1670082 "GUI: Modern theme gfx glitch
in launcher".`, because it made clip this last line of scrollbar in all
themes, which doesn't look good. In 2007 theme was written in .ini,
which is not the case now. I don't see any glitches after removing this
"fix";
- fixed how scrollbar top and bottom scroll buttons are drawn in
ThemeEngine::drawScrollbar: there were these weird magic numbers, but in
reality extra space that buttons should occupy is hardcoded in
scrollbar.cpp (ScrollBarWidget) and is just +1px.
- StorageWizardDialog is removed, along with bmps it was using;
- EditTextWidget now accepts custom font in constructor;
- ScrollContainer scrollbar now jumps to top when content height changes
so it's "overscrolled";
- IndexPageHandler now does not awaits for `code` GET-parameter, as
local webserver is no longer used to connect Storages;
- CloudManager and all corresponding Storages are updated to support
disconnecting and to notify about successful connection.
This should also fix this for other instances of ScrollContainer, though
the dialogs / widgets may require the same change.
This fixes bug Trac #10741.
The single step is the amount of scroll done when clicking once on
the scrollbar up or down arrow. It used to be 1 entry, but for the
ScrollContainer 1 entry is 1 pixel, which was too litle. Now the
single step can be set to a multiple entries.
Drawing nows happens directly when the Dialog or Widget draw methods are
called. This makes it easy to debug why a particular low level draw
method was called, by inspecting the call stack.
This replaces the notion of "buffering" by two independant ways to
control what is drawn and where:
- The active layer is used to select whether the foreground or
background part of the dialogs are rendered by the draw calls.
- The active surface is used to select if the draw calls affect the back
buffer or the screen.
The foreground layer of the active dialog is drawn directly to the
screen. Its background layer is drawn to the back buffer. This way
widgets can restore the back buffer in order to update without having to
redraw the dialog's background.
Dialogs lower in the dialog stack are drawn entirely to the back buffer.
Also remove the unused linesWidth variable and fix the hlLeftPadding and
hlRightPadding widget attributes to actually work.
There are still issues remaining with the caret in the list widget due
to the ellipsis being used to shorten long text. Ellipsis is accounted
for when drawing the text but not when computing the caret position.
