| 132 | \class QKeySequence
|
|---|
| 133 | \brief The QKeySequence class encapsulates a key sequence as used
|
|---|
| 134 | by shortcuts.
|
|---|
| 135 |
|
|---|
| 136 | \ingroup misc
|
|---|
| 137 | \ingroup shared
|
|---|
| 138 | \mainclass
|
|---|
| 139 |
|
|---|
| 140 | In its most common form, a key sequence describes a combination of
|
|---|
| 141 | keys that must be used together to perform some action. Key sequences
|
|---|
| 142 | are used with QAction objects to specify which keyboard shortcuts can
|
|---|
| 143 | be used to trigger actions.
|
|---|
| 144 |
|
|---|
| 145 | Key sequences can be constructed for use as keyboard shortcuts in
|
|---|
| 146 | three different ways:
|
|---|
| 147 |
|
|---|
| 148 | \list
|
|---|
| 149 | \o For standard shortcuts, a \l{QKeySequence::StandardKey}{standard key}
|
|---|
| 150 | can be used to request the platform-specific key sequence associated
|
|---|
| 151 | with each shortcut.
|
|---|
| 152 | \o For custom shortcuts, human-readable strings such as "Ctrl+X" can
|
|---|
| 153 | be used, and these can be translated into the appropriate shortcuts
|
|---|
| 154 | for users of different languages. Translations are made in the
|
|---|
| 155 | "QShortcut" context.
|
|---|
| 156 | \o For hard-coded shortcuts, integer key codes can be specified with
|
|---|
| 157 | a combination of values defined by the Qt::Key and Qt::Modifier enum
|
|---|
| 158 | values. Each key code consists of a single Qt::Key value and zero or
|
|---|
| 159 | more modifiers, such as Qt::SHIFT, Qt::CTRL, Qt::ALT and Qt::META.
|
|---|
| 160 | \endlist
|
|---|
| 161 |
|
|---|
| 162 | For example, \gui{Ctrl P} might be a sequence used as a shortcut for
|
|---|
| 163 | printing a document, and can be specified in any of the following
|
|---|
| 164 | ways:
|
|---|
| 165 |
|
|---|
| 166 | \snippet doc/src/snippets/code/src_gui_kernel_qkeysequence.cpp 0
|
|---|
| 167 |
|
|---|
| 168 | Note that, for letters, the case used in the specification string
|
|---|
| 169 | does not matter. In the above examples, the user does not need to
|
|---|
| 170 | hold down the \key{Shift} key to activate a shortcut specified
|
|---|
| 171 | with "Ctrl+P". However, for other keys, the use of \key{Shift} as
|
|---|
| 172 | an unspecified extra modifier key can lead to confusion for users
|
|---|
| 173 | of an application whose keyboards have different layouts to those
|
|---|
| 174 | used by the developers. See the \l{Keyboard Layout Issues} section
|
|---|
| 175 | below for more details.
|
|---|
| 176 |
|
|---|
| 177 | It is preferable to use standard shortcuts where possible.
|
|---|
| 178 | When creating key sequences for non-standard shortcuts, you should use
|
|---|
| 179 | human-readable strings in preference to hard-coded integer values.
|
|---|
| 180 |
|
|---|
| 181 | QKeySequence objects can be cast to a QString to obtain a human-readable
|
|---|
| 182 | translated version of the sequence. Similarly, the toString() function
|
|---|
| 183 | produces human-readable strings for use in menus. On Mac OS X, the
|
|---|
| 184 | appropriate symbols are used to describe keyboard shortcuts using special
|
|---|
| 185 | keys on the Macintosh keyboard.
|
|---|
| 186 |
|
|---|
| 187 | An alternative way to specify hard-coded key codes is to use the Unicode
|
|---|
| 188 | code point of the character; for example, 'A' gives the same key sequence
|
|---|
| 189 | as Qt::Key_A.
|
|---|
| 190 |
|
|---|
| 191 | \bold{Note:} On Mac OS X, references to "Ctrl", Qt::CTRL, Qt::Control
|
|---|
| 192 | and Qt::ControlModifier correspond to the \key Command keys on the
|
|---|
| 193 | Macintosh keyboard, and references to "Meta", Qt::META, Qt::Meta and
|
|---|
| 194 | Qt::MetaModifier correspond to the \key Control keys. Developers on
|
|---|
| 195 | Mac OS X can use the same shortcut descriptions across all platforms,
|
|---|
| 196 | and their applications will automatically work as expected on Mac OS X.
|
|---|
| 197 |
|
|---|
| 198 | \section1 Standard Shortcuts
|
|---|
| 199 |
|
|---|
| 200 | QKeySequence defines many \l{QKeySequence::StandardKey} {standard
|
|---|
| 201 | keyboard shortcuts} to reduce the amount of effort required when
|
|---|
| 202 | setting up actions in a typical application. The table below shows
|
|---|
| 203 | some common key sequences that are often used for these standard
|
|---|
| 204 | shortcuts by applications on four widely-used platforms. Note
|
|---|
| 205 | that on Mac OS X, the \key Ctrl value corresponds to the \key
|
|---|
| 206 | Command keys on the Macintosh keyboard, and the \key Meta value
|
|---|
| 207 | corresponds to the \key Control keys.

|
|---|
| 276 | Note that, since the key sequences used for the standard shortcuts differ
|
|---|
| 277 | between platforms, you still need to test your shortcuts on each platform
|
|---|
| 278 | to ensure that you do not unintentionally assign the same key sequence to
|
|---|
| 279 | many actions.
|
|---|
| 280 |
|
|---|
| 281 | \section1 Keyboard Layout Issues
|
|---|
| 282 |
|
|---|
| 283 | Many key sequence specifications are chosen by developers based on the
|
|---|
| 284 | layout of certain types of keyboard, rather than choosing keys that
|
|---|
| 285 | represent the first letter of an action's name, such as \key{Ctrl S}
|
|---|
| 286 | ("Ctrl+S") or \key{Ctrl C} ("Ctrl+C").
|
|---|
| 287 | Additionally, because certain symbols can only be entered with the
|
|---|
| 288 | help of modifier keys on certain keyboard layouts, key sequences intended
|
|---|
| 289 | for use with one keyboard layout may map to a different key, map to no
|
|---|
| 290 | keys at all, or require an additional modifier key to be used on
|
|---|
| 291 | different keyboard layouts.
|
|---|
| 292 |
|
|---|
| 293 | For example, the shortcuts, \key{Ctrl plus} and \key{Ctrl minus}, are often
|
|---|
| 294 | used as shortcuts for zoom operations in graphics applications, and these
|
|---|
| 295 | may be specified as "Ctrl++" and "Ctrl+-" respectively. However, the way
|
|---|
| 296 | these shortcuts are specified and interpreted depends on the keyboard layout.
|
|---|
| 297 | Users of Norwegian keyboards will note that the \key{+} and \key{-} keys
|
|---|
| 298 | are not adjacent on the keyboard, but will still be able to activate both
|
|---|
| 299 | shortcuts without needing to press the \key{Shift} key. However, users
|
|---|
| 300 | with British keyboards will need to hold down the \key{Shift} key
|
|---|
| 301 | to enter the \key{+} symbol, making the shortcut effectively the same as
|
|---|
| 302 | "Ctrl+Shift+=".
|
|---|
| 303 |
|
|---|
| 304 | Although some developers might resort to fully specifying all the modifiers
|
|---|
| 305 | they use on their keyboards to activate a shortcut, this will also result
|
|---|
| 306 | in unexpected behavior for users of different keyboard layouts.
|
|---|
| 307 |
|
|---|
| 308 | For example, a developer using a British keyboard may decide to specify
|
|---|
| 309 | "Ctrl+Shift+=" as the key sequence in order to create a shortcut that
|
|---|
| 310 | coincidentally behaves in the same way as \key{Ctrl plus}. However, the
|
|---|
| 311 | \key{=} key needs to be accessed using the \key{Shift} key on Norwegian
|
|---|
| 312 | keyboard, making the required shortcut effectively \key{Ctrl Shift Shift =}
|
|---|
| 313 | (an impossible key combination).
|
|---|
| 314 |
|
|---|
| 315 | As a result, both human-readable strings and hard-coded key codes
|
|---|
| 316 | can both be problematic to use when specifying a key sequence that
|
|---|
| 317 | can be used on a variety of different keyboard layouts. Only the
|
|---|
| 318 | use of \l{QKeySequence::StandardKey} {standard shortcuts}
|
|---|
| 319 | guarantees that the user will be able to use the shortcuts that
|
|---|
| 320 | the developer intended.
|
|---|
| 321 |
|
|---|
| 322 | Despite this, we can address this issue by ensuring that human-readable
|
|---|
| 323 | strings are used, making it possible for translations of key sequences to
|
|---|
| 324 | be made for users of different languages. This approach will be successful
|
|---|
| 325 | for users whose keyboards have the most typical layout for the language
|
|---|
| 326 | they are using.

|---|
| 329 |
|
|---|
| 330 | Key sequences similar to those used in \l{GNU Emacs}, allowing up to four
|
|---|
| 331 | key codes, can be created by using the multiple argument constructor,
|
|---|
| 332 | or by passing a human-readable string of comma-separated key sequences.
|
|---|
| 333 |
|
|---|
| 334 | For example, the key sequence, \key{Ctrl X} followed by \key{Ctrl C}, can
|
|---|
| 335 | be specified using either of the following ways:
