Constructor.
Use YUI::app() to get the singleton for this class.
Definition at line 61 of file YQApplication.cc.
|
virtual |
Open a directory selection box and prompt the user for an existing directory.
'startDir' is the initial directory that is displayed.
'headline' is an explanatory text for the directory selection box. Graphical UIs may omit that if no window manager is running.
Returns the selected directory name or an empty std::string if the user canceled the operation.
Implemented from YApplication.
Definition at line 486 of file YQApplication.cc.
|
virtual |
Open a file selection box and prompt the user for an existing file.
'startWith' is the initial directory or file.
'filter' is one or more blank-separated file patterns, e.g. "*.png *.jpg"
'headline' is an explanatory text for the file selection box. Graphical UIs may omit that if no window manager is running.
Returns the selected file name or an empty std::string if the user canceled the operation.
Implemented from YApplication.
Definition at line 503 of file YQApplication.cc.
|
virtual |
Open a file selection box and prompt the user for a file to save data to.
Automatically asks for confirmation if the user selects an existing file.
'startWith' is the initial directory or file.
'filter' is one or more blank-separated file patterns, e.g. "*.png *.jpg"
'headline' is an explanatory text for the file selection box. Graphical UIs may omit that if no window manager is running.
Returns the selected file name or an empty std::string if the user canceled the operation.

inline |
Returns 'true' if the UI automatically picks fonts, disregarding Qt standard settings.
This makes sense during system installation system where the display DPI cannot reliably be retrieved and thus Qt uses random font sizes based on that random DPI.

Change the (mouse) cursor to indicate busy status.

const QFont & YQApplication::currentFont | ( | ) |
Returns the application's default font.
Brute force approach to make sure we'll really get a complete Unicode font: Explicitly load the one font that we made sure to contain all required characters, including Latin1, Latin2, Japanese, Korean, and the characters used for glyphs.
There are many fonts that claim to be Unicode, but most of them contain just a sorry excuse for a complete Unicode character set. Qt can't know how complete a font is, so it chooses one that might be better in otherf aspects, but lacks necessary characters.

Convert logical layout spacing units into device dependent units.
A default size dialog is assumed to be 80x25 layout spacing units.
Reimplemented from YApplication.

Return a std::string for a named glyph.
Using this is discouraged in new applications.

Brute force load the heading font - see currentFont() above for more.

void YQApplication::maybeLeftHandedUser | ( | ) |
A mouse click with the wrong mouse button was detected - e.g., a right click on a push button.
The user might be left-handed, but his mouse might not (yet) be configured for left-handed use - e.g., during installation. Ask him if he would like his mouse temporarily configured as a left-handed mouse.
This status can be queried with YQApplication::leftHandedMouse().

Returns true on success (otherwise false).

void YQApplication::pickAutoFonts | ( | ) |
Determine good fonts based on defaultsize geometry and set _auto_normal_font_size and _auto_heading_font_size accordingly.
Caches the values, so it's safe to call this repeatedly.

void YQApplication::setLangFonts | ( | const std::string & | language, |
const std::string & | encoding = std::string() |

) |
Set fonts according to the specified language and encoding.
This is most important for some Asian languages that have overlaps in the Unicode table, like Japanese vs. Chinese.
Definition at line 212 of file YQApplication.cc.
|
virtual |
Set language and encoding for the locale environment ($LANG).
Load UI-internal translations (e.g. for predefined dialogs like file selection) and fonts.
'language' is the ISO short code ("de_DE", "en_US", ...).
'encoding' an (optional) encoding ("utf8", ...) that will be appended if present.
