Detailed Description

String that is able to hold international (UTF-8) strings for the user interface.

uiString is reference counted; Making a copied object is cheap.

The string will have an 'original string' of simple ASCI characters, which can be used as a 'key' but never for user display.

The string can have %1, %2, ... arguments. For these, sooner or later arguments must be provided, as in: uiString string = tr("%1 plus %2 is %3").arg( 4 ).arg( 5 ).arg( 4+5 ); ... will result in the string "4 plus 5 is 9"

As such, uiString's are suited for limited text manipulation. But if we are doing this for translated words and phrases, beware that alteration and combining is not right. Tranalations allow: Entire phrases to be concatenated Construction of lists with certain 'reasonable' separators. In no case, just glue together words and/or verbs into your own phrases.

The translation in OpendTect is done using Qt's subsystem for localization. A class that needs to use localized strings should:

1. In many cases, you can pick your stuff from the uiStrings common words and phrases defined in uistrings.h.
2. If you need specific words or phrases not in uistrings.h, then use the mTextTranslationClass(classname,packagekey) macro. The packagekey is a string that identifies your software package (probably a short plugin name). OpendTect's internal classes use the "od" package string, and can for short use the mODTextTranslationClass macro.
3. Use the tr() function for all non-standard strings. The tr() function returns a uiString that can be passed to the ui.
4. For functions not belonging to a class, use the od_static_tr function. Any function matching the *_static_tr will be interpreted by Qt's lupdate.

Notes:

Use the pre-translated strings and phrases in uistrings.h as often as possible. Examples: uiStrings::phrCannotRead() and uiStrings::sTraceNumber().

Do not juggle with words to construct phrases. This will lead to bad translations, sometimes hilarious stuff. You can however join multiple phrases into one error message. Prefer this style:

uiString msg( tr("Rendering %1 data in background").arg(objnm) ); msg.appendPhrase( tr("When finished, the image will appear") );

Note the absence of '.' at the end of lines - these phrase terminators should be added if necessary depending on the situation. Do not put them in tr() messages. There are options for different separators when appending.

All uiStrings:sXXX() start with a capital. To get the no-caps or all-caps versions, simply use toLower() and toUpper(), as in: uiStrings::sColumn().toLower()

Units of measure are not translated. Some common units may have a translation, if they are not abbreviated. For example, 'ft' is not translated, 'Feet' is. Easy to use is uiStrings::sFeet( bool abbreviation=true );

You can add 'delimiters' and 'embedding' to words ot phrases. Try to not juggle with these yourself, make sure things are handled in a decent, standard way. For example, there is a uiString::withUnit() that adds the unit (if not empty) with parentheses. Also look at parenthesize(), embed(), optional(), ...

m3Dots: This is only for menus. For buttons, the last argument 'immediate' determines the possible 3 dots at the end of the text. m3Dots is therefore for menu items only (which actually should have been designed to use the same construction, a design error). Set the flag to false and the user will expect a new dialog to pop up rather than immediate action. So the button object will add the '...' if that is the style (but that may change).
