|
|
|
|
|
|
<p>
|
|
<p> This document explains what makes an application "native" on Mac OS X.
|
|
It shows the areas where TQt/Mac is compliant, and the grey areas where
|
|
compliance is more questionable. (See also the document
|
|
<a href="mac-differences.html">TQt/Mac Issues</a>.)
|
|
<p> Normally when referring to a native application, one really means an
|
|
application that talks directly to the underlying window system and
|
|
operating system, rather than one that uses some intermediary (for
|
|
example the X11 server, or a web browser). TQt/Mac applications run as
|
|
first class citizens, just like Cocoa, Java, and Carbon applications.
|
|
<p> When an application is running as a first class citizen it means that
|
|
it can interact with specific components of the Mac OS X experience:
|
|
<p> <ul>
|
|
<li> <b>The global menubar</b><br>
|
|
<p> TQt/Mac does this via the <a href="ntqmenubar.html">TQMenuBar</a> abstraction. Mac users expect to
|
|
have a menubar at the top of the screen and TQt/Mac honors this.
|
|
<p> Additionally, users expect certain conventions to be respected, for
|
|
example the application menu should contain About, Preferences,
|
|
Quit, etc. TQt/Mac handles this automatically, although it does not
|
|
provide a means of interacting directly with the application menu.
|
|
(By doing this automatically, TQt/Mac makes it easier to port TQt/Mac
|
|
applications to other platforms.)
|
|
<p> <li> <b>Aqua</b><br>
|
|
<p> This is a critical piece of Mac OS X (documentation can be found at
|
|
<a href="http://developer.apple.com/documentation/UserExperience/Conceptual/OSXHIGuidelines/index.html">http://developer.apple.com/documentation/UserExperience/Conceptual/OSXHIGuidelines/index.html</a>).
|
|
It is a huge topic, but the most important guidelines for GUI
|
|
design are probably these:
|
|
<p> <ul>
|
|
<li> <em>Aqua look</em><br>
|
|
<p> As with Cocoa/Carbon TQt/Mac provides widgets that look like
|
|
those described in the Human Interface Descriptions. TQt/Mac's
|
|
widgets use the Appearance Manager to implement the look, so
|
|
Apple's own API's are doing the rendering (TQt/Mac <3.1 used an
|
|
emulation style with pixmaps, however this quickly proved to be
|
|
cumbersome, and unable to keep up with style changes at Apple).
|
|
<p> <li> <em>Aqua feel</em><br>
|
|
<p> This is a bit more subjective, but certainly TQt/Mac strives to
|
|
provide the same feel as any Mac OS X application (and we
|
|
consider situations where it doesn't achieve this to be bugs).
|
|
Of course TQt has other concerns to bear in mind, especially
|
|
remaining multiplatform. Some "baggage" that TQt carries is in
|
|
an effort to provide a widget on a platform for which an
|
|
equivelant doesn't exist, or so that a single API can be used to
|
|
do something, even if the API doesn't make entire sense for a
|
|
specific widget (for example pushbuttons with a popup menu are
|
|
really bevel buttons in Mac OS X, but TQt/Mac cannot guess that
|
|
this bevel button is right next to other real pushbuttons).
|
|
<p> <li> <em>Aqua guides</em><br>
|
|
<p> This is the most subjective, but there are many suggestions and
|
|
guidelines in the Aqua style guidelines. This is the area where
|
|
TQt/Mac is of least assistance. The decisions that must be made
|
|
to conform (widget sizes, widget layouts with respect to other
|
|
widgets, window margins, etc) must be made based on the user
|
|
experience demanded by your application. If your user base is
|
|
small or mostly comes from the Windows or Unix worlds, these are
|
|
minor issues much less important than trying to make a mass
|
|
market product. TQt/Mac is fully API compatible with TQt/Windows
|
|
and TQt/X11, but Mac OS X is a significantly different platform
|
|
to Windows and some special considerations must be made based on
|
|
your audience.
|
|
<p> </ul>
|
|
<p> <li> <b>Dock</b><br>
|
|
<p> Interaction with the dock is limited, but at the very least the icon
|
|
should be able to be interacted with. This can be achieved with
|
|
<a href="ntqwidget.html#setIcon">TQWidget::setIcon</a>(). The setIcon() call can be made as often as
|
|
necessary, so can be used to provide a constantly updating pixmap
|
|
that works as expected.
|
|
<p> <li> <b>Accessiblity</b><br>
|
|
<p> Although many users never use this, some users will only interact
|
|
with your applications via assistive devices. With TQt the aim is to
|
|
make this automatic in your application so that it conforms to
|
|
accepted practice on its platform (X11 accessiblity support is
|
|
still in the works due to the developing nature of its
|
|
accessibility design). With TQt 3.3 TQt/Mac will support
|
|
accessiblity, and hopefully a host of assistive devices.
|
|
<p> <li> <b>Build tools</b><br>
|
|
<p> Mac OS X developers expect a certain level of interopability
|
|
between their development toolkit and the platform's developer
|
|
tools (for example MSVC, gmake, etc). TQt/Mac supports both Unix
|
|
style Makefiles, and ProjectBuilder/Xcode project files by using
|
|
the qmake tool. For example:
|
|
<p> <pre>
|
|
qmake -spec macx-pbuilder project.pro
|
|
</pre>
|
|
|
|
<p> will generate an Xcode project file from project.pro. With qmake
|
|
you do not have to worry about rules for TQt's preprocessors (moc
|
|
and uic) since qmake automatically handles them and ensures that
|
|
everything necessary is linked into your application.
|
|
<p> TQt does not entirely interact with the development environment (for
|
|
example plugins to set a file to 'mocable' from within the Xcode
|
|
user interface). Trolltech is actively working on improving TQt's
|
|
interoperability with various IDEs, so hopefully this will be
|
|
supported soon.
