+<p>This manual presents <em>TQt Designer</em>, a tool for designing and implementing user interfaces built with the TQt multiplatform GUI toolkit. <em>TQt Designer</em> makes it easy to experiment with user interface design. At any time you can generate the code required to reproduce the user interface from the files <em>TQt Designer</em> produces, changing your design as often as you like. If you used an earlier version you will find yourself immediately productive in the new version since the interface is very similar. And you will also find new widgets and new and improved functionality which have been developed as a result of your feedback.</p>
 <p><em>TQt Designer</em> helps you build user interfaces with layout tools that move and scale your widgets (<em>controls</em> in Windows terminology) automatically at runtime. The resulting interfaces are both functional and attractive, comfortably suiting your users' operating environments and preferences. <em>TQt Designer</em> supports TQt's signals and slots mechanism for type-safe communication between widgets. <em>TQt Designer</em> includes a code editor which you can use to embed your own custom slots inside the generated code. Those who prefer to separate generated code from hand crafted code can continue to use the subclassing approach pioneered in the first version of <em>TQt Designer</em>.<!-- index Controls!Widgets --></p>
 <p>The manual introduces you to <em>TQt Designer</em> by leading you through the development of example applications. The first seven chapters are tutorials, each designed to be as self-contained as possible. Every chapter, except the first three, assumes that you are familiar with the material in chapters two and three which cover the basics of building a TQt application with <em>TQt Designer</em>. Here's a brief overview of the chapters:</p>
 <ul><li><p>Chapter one, <a href="designer-manual-2.html">Quick Start</a>, is a fast hands-on tutorial that takes you through the creation of a short, simple dialog application. The aim of this chapter is to give you a feel for how <em>TQt Designer</em> works, with explanations and details deferred to later chapters.</p>
 <li><p>Chapter two, <a href="designer-manual-3.html">Creating a Main Window Application</a>, introduces <em>TQt Designer</em> and takes you step by step through the creation of a small but fully functional application. Along the way you will learn how to create a main window with menus, toolbars and a status bar. Most of the application's implementation will be covered, but the custom dialogs are deferred until chapter three. In the course of this chapter you will use the form and property editors to customize the application. You'll also learn how to use TQt's signals and slots mechanism and <em>TQt Designer</em>'s built-in code editor to make the application functional.

 <h3><a name="2"></a>What You Should Know</h3>
 <p>This manual assumes that you have some basic knowledge of C++ and the TQt GUI toolkit. If you need to learn more about C++ or TQt there are a vast number of C++ books available, and a small but increasing number of TQt books. TQt comes with extensive online documentation and many example applications that you can try.</p>

+<p>The Enterprise Edition of TQt includes the TQt SQL module. In <a href="designer-manual-8.html">Creating Database Applications</a> we demonstrate how to build SQL applications with <em>TQt Designer</em>; this chapter requires some knowledge of SQL and relational databases.</p>
 <h3><a name="3"></a>What's New in <em>TQt Designer</em> for TQt 3.0?</h3>
 <p>This version of <em>TQt Designer</em> has a great deal more functionality than its predecessor. For example, the code for custom slots can be edited directly in <em>TQt Designer</em>; main windows with actions, toolbars and menus can be created; layouts that incorporate splitters can be used; and plugins allow you to package any number of custom widgets and make them available to <em>TQt Designer</em>. Many other enhancements have been incorporated, from small improvements in the user interface to improved efficiency, for example the ability to share pixmaps across all the forms in an application.</p>
 <p>This version of <em>TQt Designer</em> introduces project files which make it easy to switch between all the forms in an application, and to maintain a common set of database settings and images. Although subclassing is fully supported, writing code directly in <em>TQt Designer</em> offers a number of benefits which are covered in <a href="designer-manual-5.html#the-designer-approach">The Designer Approach</a> chapter. A new library, <tt>libtqui</tt>, has also been introduced which allows you to load dialogs dynamically at runtime from <em>TQt Designer</em>'s <tt>.ui</tt> files. This allows you to provide your application's users with considerable interface customizability without them needing to use C++.</p>

 <p>Grouping forms means that <em>TQt Designer</em> maintains a list of the <tt>.ui</tt> files that belong to the same project. This makes it easy to switch between forms with a single mouse click.</p>
 <h4><a name="2-2"></a>Sharing images in a image collection</h4>
-<p>In TQt 2.x's <em>TQt Designer</em> each form included the images it retquired and no images were shared. This led to duplication when several forms needed to use the same images. Furthermore the images were stored in the XML <tt>.ui</tt> files which made them large.</p>
+<p>In TQt 2.x's <em>TQt Designer</em> each form included the images it required and no images were shared. This led to duplication when several forms needed to use the same images. Furthermore the images were stored in the XML <tt>.ui</tt> files which made them large.</p>
 <p>As a workaround, we introduced a pixmap-loading function that you could define in <em>TQt Designer</em>. It then was your responsibility to provide the implementation of this function in your application code. The big disadvantage of this approach was that you couldn't see the images during the design process in <em>TQt Designer</em>. This not only makes designing a form less visually interesting, but also has a noticeable impact on geometry management.</p>
 <p>In the TQt 3.0 version of <em>TQt Designer</em> we've introduced the concept of a project image collection. If you use a project you can add images to the project's image collection, and these images can be shared and used by any of the forms you include in the project. The images are stored as PNGs (portable network graphics) in a subdirectory, <tt>images/</tt>, inside the project's directory. Whenever you modify the image collection, <em>TQt Designer</em> creates a source file which contains both the image data in binary format and a function to instantiate the images. The images are accessible by all forms in the project and the data is shared.</p>
 <p>A further benefit of using an image collection is that the images are added to the default TQMimeSourceFactory. This way they are accessible from rich-text labels, What's This? context help and even tooltips through standard HTML image tags. The <em>source</em> argument of the image tag is simply the image's name in the image collection. This also works during the design process in <em>TQt Designer</em>.</p>

 <p>In most non-trivial database applications you will want to access the database from more than one form. This is why the <tt>.db</tt> file is part of a project, not just part of a single form.</p>
 <h4><a name="2-4"></a>.pro files</h4>
 <p><em>TQt Designer</em> needs to store information on projects, for example, the list of forms, the image collection and information about available databases and how to access them. The majority of TQt users already use a project file format to create multiplatform makefiles: <tt>tmake</tt> (and with TQt 3.0 <tt>qmake</tt>) project <tt>.pro</tt> files. These files already contain the list of forms, <tt>.ui</tt> files, used in the project for <tt>uic</tt>.</p>
-<p>We've extended the sections in the <tt>.pro</tt> file to include the extra information that <em>TQt Designer</em> needs to manage projects. For example, when you add a form to your project in <em>TQt Designer</em>, it is automatically added to the FORMS section of the project file, and thus <tt>qmake</tt> will generate the retquired build rules without any further work. Similarly, the images are added to the IMAGES section and thus gets automatically compiled into your executable.</p>

 <p>We don't force you to use <tt>qmake</tt>; if you prefer another build system, for example automake/autoconf or jam, you can still continue to use it.

 <p>TQt provides excellent support for translating applications into local languages.

The Guide begins with a brief overview of the issues that must be considered, followed by chapters devoted to each role and the supporting tools provided.</p>

 <p><a href="linguist-manual-4.html">Chapter 4: Programmers</a> is for TQt programmers. It explains how to create TQt applications that are able to use translated text. It also provides guidance on how to help the translator identify the context in which phrases appear. This chapter's three short tutorials cover everything the programmer needs to do.</p>
 <h3><a name="1"></a>Overview of the Translation Process</h3>
 <p>Most of the text that must be translated in an application program consists of either single words or short phrases. These typically appear as window titles, menu items, pop-up help text (balloon help), and labels to buttons, check boxes and radio buttons.</p>
-<p>The phrases are entered into the source code by the programmer in their native language using a simple but special syntax to identify that the phrases retquire translation. The TQt tools provide context information for each of the phrases to help the translator, and the programmer is able to add additional context information to phrases when necessary. The release manager generates a set of translation files that are produced from the source files and passes these to the translator. The translator opens the translation files using <em>TQt Linguist</em>, enters their translations and saves the results back into the translation files, which they pass back to the release manager. The release manager then generates fast compact versions of these translation files ready for use by the application. The tools are designed to be used in repeated cycles as applications change and evolve, preserving existing translations and making it easy to identify which new translations are retquired. <em>TQt Linguist</em> also provides a phrase book facility to help ensure consistent translations across multiple applications and projects.</p>

 <p>Translators and programmers must address a number of issues because of the subtleties and complexities of human language:</p>
 <ul><li><p>A single phrase may need to be translated into several different forms depending on context, e.g. <em>open</em> in English might become <em></em><em>&ouml;ffnen</em>, "open file", or <em>aufbauen</em>, "open internet connection", in German.</p>
 <li><p>Keyboard accelerators may need to be changed but without introducing conflicts, e.g. "&amp;Quit" in English becomes "Avslutt" in Norwegian which doesn't contain a "Q". We cannot use a letter that is already in use -- unless we change several accelerators.</p>

 <h2 align="center">qmake Concepts</h2>
 <h3><a name="1"></a>Introducing qmake</h3>
 <p><em>qmake</em> is an easy-to-use tool from Trolltech that creates makefiles for development projects across different platforms. <em>qmake</em> simplifies the generation of makefiles so that only a few lines of information are needed to create a makefile. <em>qmake</em> can be used for any software project whether it is written in TQt or not, although it also contains additional features to support TQt development.</p>
-<p><em>qmake</em> generates a makefile based on the information in a project file. Project files are created by the developer. Project files are usually simple, but can be quite sophisticated if retquired. <em>qmake</em> can also generate projects for Microsoft Visual studio without having to change the project file.</p>

 <h3><a name="2"></a>qmake's Concepts</h3>
 <h4><a name="2-1"></a>The QMAKESPEC environment variable</h4>
 <p>Before <em>qmake</em> can be used to build makefiles, the QMAKESPEC environment variable must be set to the platform-compiler combination that is being used on the system. The QMAKESPEC environment variable tells qmake where to look to find platform and compiler specific information. This ensures that the right libraries are used, and that the generated makefile uses the correct syntax. A list of the currently supported platform-compiler combinations can be found in qt/mkspecs. Just set your environment variable to one of the directories listed.</p>

A 64x64 chunk matrix is the default for a 1024x1024 pixel canvas, where each chunk collects canvas items in a 16x16 pixel square. This default is also affected by setTiles(). You can tune this default using this function. For example if you have a very large canvas and want to trade off speed for memory then you might set the chunk size to 32 or 64.

Typically an extensible dialog will initially appear as a partial dialog, but with a" More" toggle button. If the user presses the "More" button down, the full dialog will appear. The extension widget will be resized to its sizeHint(). If orientation is Horizontal the extension widget's height() will be expanded to the height() of the dialog.

 .PP
 If you've seen regexps elsewhere they may have looked different from the ones above. This is because some sets of characters and some quantifiers are so common that they have special symbols to represent them. \fB[0-9]\fR can be replaced with the symbol \fB\\d\fR. The quantifier to match exactly one occurrence, \fB{1,1}\fR, can be replaced with the expression itself. This means that \fBx{1,1}\fR is exactly the same as \fBx\fR alone. So our 0 to 99 matcher could be written \fB^\\d{1,2}$\fR. Another way of writing it would be \fB^\\d\\d{0,1}$\fR, i.e. from the start of the string match a digit followed by zero or one digits. In practice most people would write it \fB^\\d\\d?$\fR. The \fB?\fR is a shorthand for the quantifier \fB{0,1}\fR, i.e. a minimum of no occurrences a maximum of one occurrence. This is used to make an expression optional. The regexp \fB^\\d\\d?$\fR means "from the beginning of the string match one digit followed by zero or one digits and then the end of the string".

 To access the data returned by a query, use the value() method. Each field in the data returned by a SELECT statement is accessed by passing the field's position in the statement, starting from 0. Information about the fields can be obtained via QSqlDatabase::record(). For the sake of efficiency there are no functions to access a field by name.

 .PP
 While being a technically appealing concept, masks have a big drawback: when using complex masks that cannot be expressed easily with relatively simple regions, they can be very slow on some window systems. The classic example is a transparent label. The complex shape of its contents makes it necessary to represent its mask by a bitmap, which consumes both memory and time. If all you want is to blend the background of several neighboring widgets together seamlessly, you will probably want to use setBackgroundOrigin() rather than a mask.
