I am using Eclipse + GWT. Is there a way to create a side menu in Eclipse. I need to create a fixed side menu not the menu bar. Any help appreciated.
If you're trying to make a fixed side panel for a web application using Google Web Toolkit, you can use their DockLayoutPanel class. To make a 200px sidebar on the left side of the screen, you would declare your *.ui.xml file as follows:
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<g:DockLayoutPanel unit="PX">
<g:west size="200">
<g:Label>This is the side panel!</g:Label>
</g:west>
<g:center>
<g:Label>This is the main panel.</g:Label>
</g:center>
</g:DockLayoutPanel>
</ui:UiBinder>

So I am using a dock layout panel. In the north I have a title and menubar and center has a table. My problem is when the title gets long and wraps the text, it pushed the menubar down and you can no longer see it. This is because you have to set fixed sizes for all panels except center.
I thought about moving it all to center panel but the problem is that when my table gets big and a scroll bar appears I want to always see the header and menubar even when scrolling on the table. So I cant just put everything in scroll panel.
How can I create a layout that fills these requirements:
1. Always see the title and menubar
2. Scrollable table
3. When the window is resized and text from title wraps it resizes the whole thing correctly.
here is Layout right now:
<g:DockLayoutPanel >
<g:north size="80">
<g:VerticalPanel width="100%">
<g:HorizontalPanel width="100%">
<g:HTML ui:field="title" styleName="{style.title}"></g:HTML>
</g:HorizontalPanel>
<g:HorizontalPanel styleName="{style.infoBar}" width="100%">
<g:MenuBar animationEnabled="true" styleName="{res.css.menuBar}" focusOnHoverEnabled="false" ui:field="menuBar"></g:MenuBar>
</g:HorizontalPanel>
</g:VerticalPanel>
</g:north>
<g:center>
<g:ScrollPanel>
<g:SimplePanel ui:field="content" styleName="{style.content}">Table or tree goes here
</g:SimplePanel>
</g:ScrollPanel>
</g:center>
<g:south size="20">
<g:VerticalPanel styleName="{style.footerPanel}">
<g:HTML ui:field="messageBar">Fotter text here</g:HTML>
</g:VerticalPanel>
</g:south>
</g:DockLayoutPanel>
Have you tried to use two DockLayoutPanel?
The first has the title in the center area and in the south another DockLayoutPanel with the menu in the north area and the table in the center?
If title and menu may be shown underneath each other you can put title and menu in separate north-panels (that actually works).
With that you can at least ensure that the menu gets shown.
I have create a DecoratedTabPanel in GWT
<g:HorizontalPanel ui:field="hpnlTab">
<g:DecoratedTabPanel animationEnabled="true" ui:field="tabQuran" width="499px" height="281px">
<g:Tab text="Quran">
<g:HTMLPanel width="249px" height="262px" ui:field="quranTab">
<!-- <div class="{style.qFrameMiddle}" id="middleFrame">-->
<div ui:field="quranText" class="{style.quranText}">
</div>
</g:HTMLPanel>
</g:Tab>
<g:Tab text="Translation">
<g:HTMLPanel width="7cm" height="249px"/>
</g:Tab>
</g:DecoratedTabPanel>
</g:HorizontalPanel>
Its working fine , showing the word Testing, when i click on testing, its also opens the HtmlPanel , but the problem is , its not showing TABS, just a simple text, see the image
thanks
Make sure in your ModuleName.gwt.xml has inherited standard theme or another one:
<inherits name="com.google.gwt.user.theme.standard.Standard"/>
Or you are somewhere overriding its default styles.
I am using UiBinder and a DockLayoutPanel as shown below. I am adding a custom CellTable to the ScrollPanel named "contentPanel".
When the CellTable is created for the first time, a horizonal scrollbar appears (along with the cellTableLoading.gif). Once the CellTable is finishing loading the horizontal scrollbar disappears.
How can I prevent the horizontal scrollbar from appearing in the first place?
I'd be happy to provide any other info that will help troubleshoot the problem. Many thanks!
<g:DockLayoutPanel unit='PX' styleName="{style.wrap}">
<g:north size='180'>
<g:HTMLPanel styleName='{style.header}'>
<g:Hyperlink ui:field="logoutLink" styleName="{style.login}"/>
</g:HTMLPanel>
</g:north>
<g:south size="70">
<g:HTMLPanel styleName="{style.footer}">
<g:Label>© Copyright by</g:Label>
</g:HTMLPanel>
</g:south>
<g:center>
<g:HTMLPanel styleName='{style.content}'>
<g:SimplePanel styleName='{style.left}' ui:field="navigationPanel" />
<g:ScrollPanel styleName='{style.right}' ui:field='contentPanel' />
<div style="clear: both;" ></div>
</g:HTMLPanel>
</g:center>
Impossible to tell why it happens without seeing the markup that's being generated and your CSS styles, but to turn off the scrollbars temporarily you can do the following:
// Before you load your table
contentPanel.getElement().getStyle().setOverflow(Overflow.HIDDEN);
// load your table
// ....
// after table is loaded
contentPanel.getElement().getStyle().setOverflow(Overflow.AUTO);
As a side note, you should also implement the panel inside <g:center> as a LayoutPanel instead of floated divs. It will give you a much more predictable layout:
<g:center>
<g:LayoutPanel styleName='{style.content}'>
<g:layer left="0" width="200px">
<g:SimplePanel styleName='{style.left}' ui:field="navigationPanel" />
</g:layer>
<g:layer right="0" left="200px">
<g:ScrollPanel styleName='{style.right}' ui:field='contentPanel' />
</g:layer>
</g:LayoutPanel>
</g:center>
You would also, obviously need to remove any box model related styles from .left and .right, like width and float.
I want to have some menu on all pages, and my idea is to create one page for that and include it in all other. Is it possible?
Sure it is. Create your menu (lets say it's com.something.Menu together with Menu.ui.xml), then in the including component:
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
xmlns:my='urn:import:com.something'>
<g:HTMLPanel>
Hello world!
<my:Menu />
</g:HTMLPanel>
</ui:UiBinder>
here is other example
I'm trying to embed a TabLayoutPanel inside a DockLayoutPanel but the tabs are not showing up :(
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'>
<g:DockLayoutPanel unit='PX'>
<g:north size='200'>
<g:HTML>
<h1>
My Header
</h1>
</g:HTML>
</g:north>
<g:center>
<g:TabLayoutPanel barUnit='PX' barHeight='3'>
<g:tab>
<g:header size='7'>
<b>HTML</b>
header
</g:header>
<g:Label>able</g:Label>
</g:tab>
<g:tab>
<g:customHeader size='7'>
<g:Label>Custom header</g:Label>
</g:customHeader>
<g:Label>baker</g:Label>
</g:tab>
</g:TabLayoutPanel>
</g:center>
<g:west size='192'>
<g:HTML>
<ul>
<li>Sidebar</li>
<li>Sidebar</li>
<li>Sidebar</li>
</ul>
</g:HTML>
</g:west>
</g:DockLayoutPanel>
</ui:UiBinder>
If you're seeing nothing at all, make sure that the TabLayoutPanel either (a) has an explicit size, or (b) is ultimately attached to the RootLayoutPanel (see http://code.google.com/webtoolkit/doc/latest/DevGuideUiPanels.html#Resize for more details).
If the problem is a lack of styling on the tabs (i.e., you're just seeing raw text where the tabs should be), you'll need to add some styles (the CSS rules you'll need are described in TabLayoutPanel's javadoc). There are not yet any default styles for TabLayoutPanel, but we'll be adding some soon.
The example from the JavaDoc is somewhat misleading - the bar height of 3 will hide the tab headings and a height needs to be specified for the body. Use something like:
<g:TabLayoutPanel barUnit='PX' barHeight='25' height="200px" >
or
<ui:style>
.tab {
height: 200px;
}
<g:TabLayoutPanel barUnit='PX' barHeight='25' styleName="{style.tab}" >
Also, you can find a basic CSS style for TabLayoutPanel on comment #5 in the following issue:
http://code.google.com/p/google-web-toolkit/issues/detail?id=4429
I have been having the same issue using the new TabLayoutPanel too (the tabs doesn't show up even if it's the only thing on the page). I decided to back to using the (now deprecated) TabPanel instead. Try and see if that works instead:
Example code:
<g:TabPanel width="100%" height="100%" ui:field="gwtimeTabPanel">
<g:Tab>
<g:TabHTML>Tab title</g:TabHTML>
<g:FlowPanel>
<!-- tab contents goes here -->
</g:FlowPanel>
</g:Tab>
</g:TabPanel>
For the people who mainly use Java code to define the UI.
Explenation
You should set the size of the parentpanel of the TabLayoutPanel and of the TabLayoutPanel itself. For instance I had a VerticalPanel and a TabLayoutPanel, I added this TabLayoutPanel to the VerticalPanel (which makes it the parentpanel of TabLayoutPanel) like this:
veticalPanel.add(tabLayoutPanel);
RootPanel.get().add(verticalPanel);
which did nothing...
Answer
you should declare the size of your panels like this
//set size
vertialPanel.setSize("100%","100%");
tabLayoutPanel.setSize("100%","100%")
RootPanel.get().add(verticalPanel);
