|
||
|
|
<p>Start up <em>Qt Designer</em> to invoke the <em>Qt Designer New/Open</em> dialog. This dialog contains three tabs to use depending on what you want to do once you start up <em>Qt Designer</em>.</p>
|
||
|
|
<h5><a name="2-1-1"></a>The New File/Project Tab</h5>
|
||
|
|
<p>This tab is the default when you start up <em>Qt Designer</em>. Choose to start a new project or to create a file by selecting the appropriate icon from the window. For more information about the different file types available, see the <a href="designer-manual-13.html#3">The File Dialogs</a> section.</p>
|
||
|
|
<p>Click the "Don't show this dialog in the future" checkbox to hide the dialog the next time you start up <em>Qt Designer</em>.</p>
|
||
|
|
<h5><a name="2-1-2"></a>The Open File/Project Tab</h5>
|
||
|
|
<p align="center"><img align="middle" src="rd-startdesigntab2.png" width="584" height="446">
|
||
|
|
</p>
|
||
|
|
<blockquote><p align="center"><em>Open File/Project</em></p></blockquote>
|
||
|
|
<p>Click this tab to open an already existing file or project. The tab shows the current directory and default file type. To choose a different directory, click the 'Look In' combobox. Choose a file and the name will appear in the 'File Name' combobox. To choose a different file type, click the 'File Type' combobox. Click the 'Create New Folder' toolbar button to create a new directory. Click the 'List View' toolbar button to view folders and files in a list with only the names showing. Click the 'Details' toolbar button to view the folders and file names along with their size, type, date, and attributes. Click the Size, Type, Date, or Attributes column headers to sort the folders or files.</p>
|
||
|
|
<p>Click <b>OK</b> to open the selected file. Click <b>Cancel</b> to leave the dialog without opening a new file.</p>
|
||
|
|
<h5><a name="2-1-3"></a>The Recently Opened Tab</h5>
|
||
|
|
<p>This tab displays all of the recently opened files or projects in a window. Select a file or project and then click <b>OK</b> to open it.</p>
|
||

|
<h3><a name="3"></a>The File Dialogs</h3>
|
||
|
|
<p align="center"><img align="middle" src="mw-newfile.png" width="565" height="330">

<blockquote><p align="center"><em>New File</em></p></blockquote>
|
||
|
|
<a name="dialog-file-new"></a><h4><a name="3-1"></a>New File Dialog</h4>
|
||
|
|
<p>Click <b>File|New</b> (or press <b>Ctrl+N</b>) to invoke the <em>New File</em> dialog. This dialog offers four kinds of files to choose from: C++ Project, Forms, Source files, and Main files.</p>
|
||
|
|
<p>The 'Insert Into' drop-down combobox lists the open projects, defaulting to the current project. New files are added to the project displayed in this combobox. To add a new file to a different project, choose the project you want to use in the 'Insert Into' combobox.</p>
|
||
|
|
<p>The 'Dialog' file type is highlighted by default when the <em>New File</em> dialog pops up. Click on the file type you want to use and click <b>OK</b> to create it. Click <b>Cancel</b> to leave the dialog without creating a new file. Note that if you select C++ Project, the 'Insert Into' combobox will be disabled, since it is not possible to insert a new C++ Project into an existing project.</p>
|
||
|
|
<h5><a name="3-1-1"></a>C++ Project Files</h5>
|
||
|
|
<p>Click <b>C++ Project</b> to start a new project. This option invokes the <a href="designer-manual-13.html#5-4">Project Settings Dialog</a>. C++ projects are saved as <tt>.pro</tt> files, which include the information <em>Qt Designer</em> needs to manage projects. When you add a form to your project in <em>Qt Designer</em>, it is automatically added to the FORMS section of the project file. The <tt>.pro</tt> file contains the list of forms (<tt>.ui</tt> files) used in the project. <em>Qt Designer</em> reads and writes <tt>.ui</tt> files, e.g. form.ui. The uic (user interface compiler) creates both a header file, e.g. form.h, and an implementation file, e.g. form.cpp, from the <tt>.ui</tt> file.</p>
|
||
|
|
<h5><a name="3-1-2"></a>Dialog Forms</h5>
|
||
|
|
<p>Click <b>Dialog</b> to create a plain dialog form. Typically, this type of form is used to present the user with configuration options, or to present related sets of choices, for example, printer setting dialogs and find and replace dialogs.</p>
|
||
|
|
<h5><a name="3-1-3"></a>Wizard Forms</h5>
|
||
|
|
<p>Click <b>Wizard</b> to create a wizard form. A wizard is a special type of input dialog that consists of a sequence of dialog pages. A wizard's purpose is to assist a user by automating a task by walking the user through the process step by step. Wizards are useful for complex or infrequently occurring tasks that people may find difficult to learn or do. Initially the wizard form consists of a single dialog page. Use the right click context menu to add additional pages and to change page titles.</p>
|
||
|
|
<h5><a name="3-1-4"></a>Widget Forms</h5>
|
||
|
|
<p>Click <b>Widget</b> to create a form whose superclass is QWidget rather than QDialog.</p>
|
||
|
|
<h5><a name="3-1-5"></a>Main Window Form</h5>
|
||
|
|
<p>Click <b>Main Window</b> to invoke the <a href="designer-manual-14.html#2">Main Window Wizard</a>. This wizard is used to create actions, menu options and toolbars through which the user can invoke actions. This form is used to create typical main-window style applications.</p>
|
||
|
|
<h5><a name="3-1-6"></a>Configuration Dialog Form</h5>
|
||
|
|
<p>Click <b>Configuration Dialog</b> creates a form with a listbox on the left, and a tabwidget filling the body of the form, along with Help, OK and Cancel buttons.</p>
|
||
|
|
<h5><a name="3-1-7"></a>Dialog with Buttons (Bottom) Form</h5>
|
||
|
|
<p>The <b>Dialog with Buttons (Bottom)</b> form is a template with default buttons at the bottom of the form.</p>
|
||
|
|
<h5><a name="3-1-8"></a>Dialog with Buttons Form (Right)</h5>
|
||
|
|
<p>The <b>Dialog with Buttons (Right)</b> form is a template with default buttons at the right of the form.</p>
|
||
|
|
<h5><a name="3-1-9"></a>Tab Dialog Form</h5>
|
||
|
|
<p>The <b>Tab Dialog</b> form has a tab widget as its central widget, along with Help, OK and Cancel buttons along the bottom.</p>
|
||
|
|
<h5><a name="3-1-10"></a>C++ Source File</h5>
|
||
|
|
<p>Click <b>C++ Source File</b> to create a new empty C++ file. The file will automatically be added to the project when it is saved.</p>
|
||
|
|
<h5><a name="3-1-11"></a>C++ Header File</h5>
|
||
|
|
<p>Click <b>C++ Header File</b> to create a new empty C++ header file. The file will automatically be added to the project when it is saved.</p>
|
||
|
|
<h5><a name="3-1-12"></a>C++ Main File</h5>
|
||
|
|
<p>Click <b>C++ Main File</b> to invoke the <a href="designer-manual-13.html#3-1-12-1">Configure Main-File Dialog</a> which will create a basic <tt>main.cpp</tt> file automatically. C++ Main file is not an option if you do not have a project open. In addition, this file type is not avalable in the <em>Qt Designer New/Open</em> dialog because you cannot create a main.cpp file without creating a project.</p>

|
|
<p>Click <b>File|New|C++ Main-File</b> to invoke the <em>Configure Main-File</em> dialog. Use this dialog to configure the main file and its forms.</p>
|
||
|
|
<p>To change the default file name, type it in the 'Filename' line edit. Choose the form to use as the application's main form from the line edit by clicking it.</p>
|
||
|
|
<p>Click <b>OK</b> to accept the configurations and <em>Qt Designer</em> will create a default <tt>main.cpp</tt> file. Click <b>Cancel</b> to leave the dialog.</p>
|
||
|
|
<p>Note for database programmers: If you create a <tt>main.cpp</tt> file using <em>Qt Designer</em>, this file will <em>not</em> include the <tt>createConnections()</tt> function. We do not include this function because it needs the username and password for the database connection, and you may prefer to handle these differently from our simple example function. As a result, applications that preview correctly in <em>Qt Designer</em> will not run unless you implement your own database connections function.</p>

<blockquote><p align="center"><em>Form Settings</em></p></blockquote>
|
||
|
|
<p>Click <b>Edit|Form Settings</b> to invoke the <em>Form Settings</em> dialog. Use this dialog to save the form's settings, pixmap, and layout properties.</p>
|
||
|
|
<h5><a name="4-3-1"></a>Settings</h5>
|
||
|
|
<p>In the Settings section, you can change or add the name of the class that will be created by typing in the 'Class Name' line edit. Note that the default name is the form name, but it can be changed. You can also enter text to the 'Comment' and 'Author' line edits or leave them blank, since they are not required.</p>
|
||
|
|
<h5><a name="4-3-2"></a>Pixmaps</h5>
|
||
|
|
<p>The default (for projects) is 'Project Imagefile'. This is the recommended option. Images are handled automatically, with <em>Qt Designer</em> storing the images in a subdirectory, and <tt>uic</tt> producing code that contains the images and the necessary supporting code. Each image is stored just once, no matter how many forms it is used in.</p>
|
||
|
|
<p>If you do not want <em>Qt Designer</em> to handle the images, (or are not using a project) choose either 'Save Inline' or 'Use Function'. 'Save Inline' saves the pixmaps in the <tt>.ui</tt> files. The disadvantage of this approach is that it stores images in the forms in which they're used, meaning that images cannot be shared across forms. Click 'Use Function' to use your own icon-loader function for loading pixmaps. Type the function's name (with no signature) in the 'Use Function' line edit. This function will be used in the generated code for loading pixmaps. Your function will be called with the text you put in the pixmap property (e.g. the image name) whenever an image is required.</p>
|
||
|
|
<h5><a name="4-3-3"></a>Layouts</h5>
|
||
|
|
<p>Click the 'Default Margin' spinbox or the 'Default Spacing' spinbox to change the default layout settings of the current form.</p>
|
||
|
|
<p>To use the functions in the generated code to dynamically retrieve values for the layout's default margin and spacing, check the Use Functions chechbox. In the Margin and Spacing line edits, specify the function names (no signatures or parantheses) which should be used to retrieve the margin and spacing.</p>
|
||
|
|
<p>Click <b>OK</b> to accept changes to the form settings. Click <b>Cancel</b> to leave the dialog without making any changes.</p>
|
||
|
|
<a name="dialog-edit-preferences"></a><h4><a name="4-4"></a>Preferences Dialog</h4>
|
||
|
|
<p>Click <b>Edit|Preferences</b> to invoke the <em>Preferences</em> dialog. This dialog has a tab for 'General' preferences. If you have the C++ Editor plugin, the dialog will also have a tab for the C++ Editor.</p>

||
|
|
<h5><a name="4-4-1"></a>General Tab</h5>

|
|
</p>
|

|
<blockquote><p align="center"><em>Preferences- General Tab</em></p></blockquote>
|
||
|
|
<p>The 'General' tab has sections for Background, Grid, General, File Saving, and Plugin Paths.</p>
|
||
|
|
<p>The Background section defaults to 'Pixmap'. To change the default, click the <b>Select a Pixmap</b> button next to the 'Pixmap' radio button to invoke the <em>Choose a Pixmap... Dialog</em>. Click the 'Color' radio button to change the background to a color instead of a pixmap. Click the <b>Choose a Color</b> button located to the right of the 'Color' radio button to invoke the <em>Select Color Dialog</em>.</p>
|
||
|
|
<p>The 'Grid' section has options for customizing the grid on the form. The 'Show Grid' checkbox located above the 'Grid' section is checked by default. Developers using <em>Qt Designer</em> almost always use Qt's layouts to design their forms and rarely make any use of the grid. The grid is provided for the rare occasions when a form is created using widgets with fixed sizes and positions. When 'Show Grid' is checked, you can customize the grid's appearance. When it is unchecked, the 'Grid' section is disabled. The 'Snap to Grid' checkbox is also checked by default. When it is checked, widgets are placed on a dot (snap to the grid) using the X|Y resolution. When it is unchecked, the 'Grid-X' and 'Grid-Y' spin boxes are disabled. Click the 'Grid X' and 'Grid Y' spinboxes to customize the grid settings for all forms.</p>
|

|

<p>Custom widgets are created in code. They may contain a combination of existing widgets but with additional functionality, slots and signals, or they may be written from scratch, or a mixture of both. A custom widget is often a specialization (subclass) of another widget or a combination of widgets working together or a blend of both these approaches. If you simply want a collection of widgets in a particular configuration it is easiest to create them, select them as a group, and copy and paste them as required within <em>Qt Designer</em>. Custom widgets are generally created when you need to add new functionality to existing widgets or groups of widgets. To add create a new widget, click the <b>New Widget</b> button. You will find more information about adding new widgets in the 'Definitions Section'. To load a file which contains descriptions of custom widgets, click the <b>Load Descriptions</b> button.
