<title>Toolbar skapad med Glade</title>
<media type="image" mime="image/png" src="media/toolbar.png"/>
<p>Detta exempel liknar <link xref="toolbar.vala"/>, förutom att vi använder Glade för att skapa verktygsfältet i en XML .ui-fil.</p>
<p>För att skapa verktygsfältet med <link href="http://glade.gnome.org/">gränssnittsbyggaren Glade</link>:</p>
<steps>
<item><p>Öppna Glade, och spara filen som <file>toolbar_builder.ui</file></p>
<p><media type="image" src="media/glade_ui.png" width="900"> Skärmbild av Glades användargränssnitt </media></p>
</item>
<item><p>Under <gui>Behållare</gui> på vänster sida, högerklicka på verktygsfältsikonen och välj <gui>Lägg till komponent som toppnivå</gui>.</p>
<p><media type="image" src="media/glade_select_toolbar.png"> Skärmbild av verktygsfältsikon i Glades användargränssnitt </media></p>
</item>
<item><p>Under the <gui>General</gui> tab on the bottom right, change the <gui>Name</gui> to <input>toolbar</input> and <gui>Show Arrow</gui> to <gui>No</gui>.</p>
<p><media type="image" src="media/glade_toolbar_general.png"> Skärmbild av fliken Allmänt </media></p>
</item>
<item><p>Under fliken <gui>Gemensamma</gui>, ställ in <gui>Vågrät expansion</gui> till <gui>Ja</gui>.</p>
<p><media type="image" src="media/glade_toolbar_common.png"> Skärmbild av fliken Gemensam </media></p>
</item>
<item><p>Högerklicka på verktygsfältet i det övre högra hörnet och välj <gui>Redigera</gui>. Fönstret <gui>Verktygsfältsredigerare</gui> kommer visas.</p>
<p><media type="image" src="media/glade_toolbar_edit.png"> Skärmbild av var högerklick ska ske för att redigera verktygsfält. </media></p>
</item>
<item><p>We want to add 5 ToolButtons: New, Open, Undo, Fullscreen and Leave Fullscreen. First, we will add the New ToolButton.
</p>
<steps>
<item><p>Under fliken <gui>Hierarki</gui>, klicka på <gui>Lägg till</gui>.</p></item>
<item><p>Ändra namnet på detta ToolItem till <input>new_button</input>.</p></item>
<item><p>Rulla ner och ställ in <gui>Är viktig</gui> till <gui>Ja</gui>. Detta kommer få etiketten för vår ToolButton att visas när verktygsfältet visas.</p></item>
<item><p>Ange <gui>Åtgärdsnamn</gui>et: <input>app.new</input>.</p></item>
<item><p>Ändra <gui>Etikett</gui> till <input>Ny</input>.</p></item>
<item><p>Select the <gui>New</gui> Stock Id from the drop down menu, or type <input>gtk-new</input>.</p></item>
</steps>
<p>
Repeat the above steps for the remaining ToolButtons, with the following properties:
</p>
<table frame="all" rules="rows">
<thead>
<tr>
<td><p>Name</p></td>
<td><p>Är viktig</p></td>
<td><p>Åtgärdsnamn</p></td>
<td><p>Label</p></td>
<td><p>Standard-ID</p></td>
</tr>
</thead>
<tbody>
<tr>
<td><p>open_button</p></td>
<td><p>Ja</p></td>
<td><p>app.open</p></td>
<td><p>Öppna</p></td>
<td><p>gtk-open</p></td>
</tr>
<tr>
<td><p>undo_button</p></td>
<td><p>Ja</p></td>
<td><p>win.undo</p></td>
<td><p>Ångra</p></td>
<td><p>gtk-undo</p></td>
</tr>
<tr>
<td><p>fullscreen_button</p></td>
<td><p>Ja</p></td>
<td><p>win.fullscreen</p></td>
<td><p>Helskärmsläge</p></td>
<td><p>gtk-fullscreen</p></td>
</tr>
<tr>
<td><p>leave_fullscreen_button</p></td>
<td><p>Ja</p></td>
<td><p>win.fullscreen</p></td>
<td><p>Lämna helskärmsläge</p></td>
<td><p>gtk-leave-fullscreen</p></td>
</tr>
</tbody>
</table>
<media type="image" src="media/glade_toolbar_editor.png">
</media>
</item>
<item><p>Stäng <gui>Verktygsfältsredigerare</gui>n.</p>
</item>
<item><p>When our program will first start, we don't want the <gui>Leave Fullscreen</gui> ToolButton to be visible, since the application will not be in fullscreen mode. You can set this in the <gui>Common</gui> tab, by clicking the <gui>Visible</gui> property to <gui>No</gui>. The ToolButton will still appear in the interface designer, but will behave correctly when the file is loaded into your program code.</p>
<p><media type="image" src="media/glade_visible_no.png">
Setting the visible property to No
</media></p>
</item>
<item><p>Spara ditt arbete och stäng Glade.</p>
</item>
<item><p>The XML file created by Glade is shown below. This is the description of the toolbar. At the time of this writing, the option to add the class Gtk.STYLE_CLASS_PRIMARY_TOOLBAR in the Glade Interface did not exist. We can manually add this to the XML file. To do this, add the following XML code at line 9 of <file>toolbar_builder.ui</file>:</p>
<code><![CDATA[
<style>
<class name="primary-toolbar"/>
</style>
]]></code>
<p>If you do not add this, the program will still work fine. The resulting toolbar will however look slightly different then the screenshot at the top of this page.</p>
