Previously, IconButton instances to be added to button boxes were
allocated with new, but never freed with delete.
unique_ptr makes sure the buttons will be freed along with the button
box that owns them, or when code calls ButtonBox::clear.
The destructor of ButtonBox has been made redundant by this change, so
it's gone.
Browsing the user's wallpaper directory will simply add no new files
to the list of wallpapers available if the directory doesn't exist.
WallpaperDialog::exec doesn't need to care about that.
Because wallpapers are files, not directories, also don't return
directories in the result. The code that makes the wallpapers list
calls FileLister::getFiles and ignores directories anyway.
Browsing the user's translations directory will simply add no new files
to the list of translations available if the directory doesn't exist.
GMenu2X::showSettings() doesn't need to care about that.
Because translations are files, not directories, also don't return
directories in the result. The code that makes the translations list
calls FileLister::getFiles and ignores directories anyway.
A file existence check is already performed, atomically with respect to
the filesystem, by ifstream's constructor. The result of this check is
available using ifstream::is_open().
0 is the default clock value, which doesn't get written to link files
if it's not changed. The clock was previously uninitialised before
reading link files, so it would get written with a random value if
there was none before.
Instead of splitting the filter for every file in FileLister::browse,
the filter is split immediately in FileLister::setFilter, improving
performance.
getFilter is removed because it was unused. This also removes the need
to update the return type to 'const std::vector&' in the method and
rewrite its callers.
Configuration of the FileLister is now left to the subclasses of
BrowseDialog, as the construction of a FileLister and its configuration
(to show or hide directories and files) have been separated.
This allows deleting the destructors of BrowseDialog's subclasses,
which existed solely to delete a FileLister object constructed by
each subclass.
The allocation of a BrowseDialog now also implies allocating enough
space for its FileLister, so remove the check for fl being nullptr in
BrowseDialog::exec().
The constructor now has zero arguments. showDirectories and showFiles
are now set using setter methods.
FileLister::browse is now the sole way to start a scan for files and
directories, replacing the initial path in the constructor and the
setPath method. It allows merging results from multiple directories
as before.
This is all to make explicit how many times the costly task of browsing
a directory is actually carried out.
Instead of showing 'R:', 'G:', 'B:' and 'A:', which take up a lot of space
and can overlap in standard fonts, the selection rectangle surrounding the
number is red, green, blue or gray, and the text is shorter.
This will allow the labels for the skin colors to be longer for translations
as well, given that their values are shown less wide.
Instead of checking which input configuration file exists among 2
choices, then asking InputManager to load that file, InputManager
itself now performs the resolution based on whether ifstream::is_open
returns true for each choice.
The existence of modifications to the skin configuration in the home
directory is now checked with ifstream::is_open, and the system's skin
configuration is used if that returns false.
A file existence check is already performed, atomically with respect to
the filesystem, by ifstream's constructor. The result of this check is
available using ifstream::is_open().
Setting values are now displayed 10 pixels to the right of setting names, as
passed to MenuSetting::draw.
This commit also contains the following cleanups:
* The height of a row is passed to MenuSetting's draw and touchscreen methods.
* MenuSettingRGBA's magic constant (36) to separate the text for a color's
four components is now a named constant.
* MenuSettingRGBA's color preview squares are now rowHeight - 2 pixels tall,
and have a white border surrounded by a black border to help view the color
it contains in both light and dark themes.
* The rectangle behind the selected setting's name is now drawn by that
setting's drawSelected method.
Setting descriptions and help prompts now appear fully even if they are longer
than the screen allows. Translations do not need to worry about allowed text
being wider than the screen in some fonts anymore.
The constructors of those classes now accept a string to be wrapped, instead
of a vector to be modified with split lines inserted into its middle.
Along with this conversion, manuals for applications stored in OPK packages
are now transferred into a string without garbage at the end.
This implementation is based on the implementation in TextDialog::preProcess,
with one major difference: it works on the entire input string, copies it much
less as part of its function, and tries to quickly establish a small search
space for the length of the beginning split of each line.
With most standard fonts and sizes, this means up to 9 computations of metrics
per output line.
Multi-line message boxes had the incorrect height.
I also took the opportunity to make named constants out of magic numbers
making up the various message box dimensions.
This affects manuals, About GMenu2X, and the Log Viewer.
Instead of trying to compute the width of the entire string, then backing
off one word at a time, TextDialog::preProcess now performs a binary search
on Font::getTextWidth(string) and backs off to the last fitting space, if
there is one, at the last moment.
In Japanese and Chinese text, words are not usually separated by spaces.
Text in these languages is now wrapped when it would reach the edge of the
screen.
This allows for faster scrolling between section links, in file and directory
selectors, and in manuals, without repeatedly pressing buttons.
The setting's unit is repetitions per second. Its default value is set to
10, and anything between 0 (disabled) and 20 (50 ms) is acceptable.
Grabbing &(instance of GMenu2X).confInt["buttonRepeatRate"] is unsafe, because
the storage for the slot may move as the slot is deleted or added. Instead, a
callback jumps back into the context of an InputManager so the value can be
read from a GMenu2X object's configuration.
A GMenu2X object is also passed to InputManager::init.
Previously, one would check the value in &confInt["someKey"] by passing a
reference to it to evalIntConf. However, because this passing of the reference
went through std::unordered_map::operator[], it created a slot with the named
key and initialised its value with the default constructor of int, which
placed 0 there, if it didn't exist. If the value of 0 was acceptable for the
setting, then 0 as the value selected by the user was indistinguishable from
a slot that had been just created and had to be set to its default.
Now, the std::unordered_map is passed along with the key so that evalIntConf
can check whether the key exists and, if it doesn't exist, set the value to
its default.
Include utilities.h in gmenu2x.h instead of the reverse. One type definition
used by utilities.cpp is moved there (ConfIntHash) and for consistency
ConfStrHash is moved there as well.
Asking FreeType for metrics before asking it for a render, when rendering
would compute the metrics anyway, is wasteful. Now the width of text, for
horizontal alignment purposes, is simply the width of the render.
In well-described fonts, this enables multi-line text (e.g. in manuals) to be
more readable.
The term "height" is also replaced with "line spacing" in Font's code.
This does away with per-link selector directories in link files. It is assumed
that, if a user has access to write files to be launched by an application at
some location, he or she also has access to write files in the previews/
subdirectory under it.
The alpha change is so that:
* some of the background is still visible, which includes the name of the
application for which the selector is being called, its description, and
text in the status bar;
* the preview, if bright, does not obscure the file names too much.
Selector previews are now shown full-screen (320x240) instead of being a
160x160px square on the right.
These issues are fixed:
* loadPNG gave RGBA surfaces unconditionally. Now it gives RGB surfaces if
its second parameter, defaulting to true, is false. This fixes adding per-
surface alpha values, because an RGBA surface ignores its per-surface value.
* Surface::loadImage is updated to receive a third parameter, defaulting to
true, to determine whether alpha is loaded.
* SurfaceCollection::defaultAlpha was never used.
* SurfaceCollection::defaultAlpha defaulted to false, so even if it were used,
it would have loaded images without alpha.
This commit ensures that a fully constructed Font object will not crash
gmenu2x when it is used, even if loading the font or initialising SDL_ttf
altogether has failed. Instead, it will render no text, but icons and
images are still drawn.
The proper way to signal an error would be to throw an exception and fail
to construct the Font object. However, gmenu2x does not use exceptions.
Since 2002-09-03, SDL_ttf performs reference counting on TTF_Init and
TTF_Quit. If two fonts were loaded concurrently via the Font class and
one was destructed, the destructor of the first object would call TTF_Quit,
making the second object unusable. The constructor now calls TTF_Init
unconditionally to prevent this situation.
The reference counting behavior was introduced in this SDL_ttf commit:
