Is there a way to create a file with specific extension. Currently im creating a html kind file. Is there a way to give specific extension to the file while creating? Maybe .css or .js etc?
<extension
point="org.eclipse.ui.newWizards">
<category id="com.ui.category" name="XXX Project">
</category>
<wizard
category="com.ui.category"
id="ui.wizard.NewFileWizard"
name="Create a new File"
icon="icons/new_project.png"
class="org.eclipse.ui.wizards.newresource.BasicNewFileResourceWizard"
project="true"
>
</wizard>
</extension>
You will have to create your own wizard to do this, extending BasicNewFileResourceWizard
The minimum code would be something like this:
public class FileExtNewFileWizard extends BasicNewFileResourceWizard
{
public FileExtNewFileWizard()
{
super();
}
#Override
public void addPages()
{
super.addPages();
// Get the page created by `super.addPages` and set the default file extension
WizardNewFileCreationPage page = (WizardNewFileCreationPage)getPage("newFilePage1");
page.setFileExtension("css");
}
}

I create a file creation page by extending class WizardNewFileCreationPage. What I am trying to do is to hide the help button on the left bottom corner. Any suggestions on how to do this?
Thank you.
Call this method: Wizard#setHelpAvailable(false)
Refer API here
I called this method but not working. See the following:
public class NewTDLDiagram extends Wizard implements INewWizard {
private NewDiagramFilePage page;
public NewTDLDiagram() {
// TODO Auto-generated constructor stub
setHelpAvailable(false);
}
...
}
This class is registered as an extension point of org.eclipse.ui.newWizards:
<extension
point="org.eclipse.ui.newWizards">
<wizard
class="com.abc.graphicview.ui.NewDiagram"
icon="icons/NewSmdWizard.gif"
id="com.abc.graphicview.ui.diagrawizard"
name="Diagram"
project="false">
<selection
class="org.eclipse.core.resources.IResource">
</selection>
</wizard>
</extension>
Many people are using Consolas for their primary programming font but unfortunately there is no way to change line height in Eclipse so it looks kinda ugly as it is shown below:
I was wondering if there is anyone who solved this by adding some extra space between lines or simply changing the font itself which has longer height now.
It would be nice to share it with us here on Stackoverflow.
There are some topics I've found while searching for this but none of them were what I am looking for:
How can I change line height / line spacing in Eclipse?
https://stackoverflow.com/questions/15153938/improved-line-spacing-for-eclipse?lq=1
and so on...
Some of them designed their own fonts (such as Meslo Font) by modifying the existing ones so it would be nice if you could share your modified Consolas font.
As mentioned in one of the answers you reference the underlying StyledText control does have a setLineSpacing method, but the existing editors do not use it.
The CSS styling code in Eclipse 4.3 does provide a way to access this but it requires writing a plugin to extend the CSS in order to do so.
The plugin.xml for the plugin would look like this:
<plugin>
<extension
point="org.eclipse.e4.ui.css.core.elementProvider">
<provider
class="linespacing.LineSpacingElementProvider">
<widget
class="org.eclipse.swt.custom.StyledText"></widget>
</provider>
</extension>
<extension
point="org.eclipse.e4.ui.css.core.propertyHandler">
<handler
adapter="linespacing.StyledTextElement"
composite="false"
handler="linespacing.LineSpacingPropertyHandler">
<property-name
name="line-spacing">
</property-name>
</handler>
</extension>
</plugin>
which declares a CSS element provider LineSpacingElementProvider which would be:
public class LineSpacingElementProvider implements IElementProvider
{
#Override
public Element getElement(final Object element, final CSSEngine engine)
{
if (element instanceof StyledText)
return new StyledTextElement((StyledText)element, engine);
return null;
}
}
The StyledTextElement this provides is just:
public class StyledTextElement extends ControlElement
{
public StyledTextElement(StyledText control, CSSEngine theEngine)
{
super(control, theEngine);
}
}
The second declaration in the plugin.xml is a CSS property handler for a property called line-spacing
public class LineSpacingPropertyHandler extends AbstractCSSPropertySWTHandler implements ICSSPropertyHandler
{
#Override
protected void applyCSSProperty(Control control, String property, CSSValue value, String pseudo, CSSEngine engine) throws Exception
{
if (!(control instanceof StyledText))
return;
StyledText text = (StyledText)control;
if ("line-spacing".equals(property))
{
int pixelValue = (int)((CSSPrimitiveValue)value).getFloatValue(CSSPrimitiveValue.CSS_PX);
text.setLineSpacing(pixelValue);
}
}
#Override
protected String retrieveCSSProperty(Control control, String property, String pseudo, CSSEngine engine) throws Exception
{
return null;
}
}
With a plugin containing this installed you can then modify one of the existing CSS style sheets to contain:
StyledText {
line-spacing: 2px;
}
You better choose different fonts. Don't just stick to things. Try new things and accept them. :D I was also using Consolas. But now I am using Courier New and they are pretty fine. If you have 21" or larger display you can use Courier New at 12 or 14 size. Once you use this you will get used to it as you are with Consolas now :P
You could try Fira Mono. See some screenshots here. Small sizes look good too.
I want to use the Eclipse mechanism to set default preferences in my RCP application. Therefore I extended the class AbstractPreferenceInitializer to set my default preferences:
public class PreferenceInitializer extends AbstractPreferenceInitializer {
#Override
public void initializeDefaultPreferences() {
IPreferenceStore preferenceStore = PlatformUI.getPreferenceStore();
preferenceStore.setDefault("xyz", xyz);
preferenceStore.setDefault("abc", false);
}
}
Then I defined the extension point:
<extension point="org.eclipse.core.runtime.preferences">
<initializer class="com.abc.PreferenceInitializer">
</initializer>
</extension>
But unfortunately, the initializer won't get called during startup (whereas Eclipse's WorkbenchPreferenceInitializer will be called).
Can someone give me a hint, what to do, to get this run?
Your preference initializer code won't get called until those default values are needed (rather than on application startup, which I'm guessing was your expectation).
If you have yourself a preference page that contains some FieldEditors using your preference names, your preference initializer will get called when you go to the Preferences dialog and select that preference page.
Something along the lines of:
public class MyPreferencePage extends FieldEditorPreferencePage implements IWorkbenchPreferencePage {
public void createFieldEditors() {
Composite parent = getFieldEditorParent();
addField(new StringFieldEditor(Constants.PREFERENCES.FILE_COMPARE_TOOL_LOCATION, "File compare tool location", parent));
addField(new StringFieldEditor("xyz", "XYZ Value", parent));
addField(new BooleanFieldEditor("abc", "Enable the ABC widget", parent));
}
}
And of course, an extension point for the page:
<extension point="org.eclipse.ui.preferencePages">
<page
class="whatever.package.MyPreferencePage"
id="whatever.package.MyPreferencePage"
name="MyPrefs">
</page>
</extension>
How do I set different localized strings in different visual states in WP7 using Blend without any code behind?
I can set different non-localized strings in different visual states (although it flickers). That works, but how about localized strings?
If I change the string using data binding in Blend, Blend just overrides the data binding in Base state and not the actual state where I'm recording.
EDIT:
This is how I localize my strings:
I have a resources file named AppPresources.resx. Then I would do this in code:
// setting localized button title
mainButton.Content = AppResources.MainButtonText;
Then I have a GlobalViewModelLocator from MVVM Light Toolkit with the following Property for Databinding.
private static AppResources _localizedStrings;
public AppResources LocalizedStrings
{
get
{
if (_localizedStrings == null)
{
_localizedStrings = new AppResources();
}
return _localizedStrings;
}
}
And in xaml file:
<Button x:Name="mainButton" Content="{Binding LocalizedStrings.MainButtonText, Mode=OneWay, Source={StaticResource Locator}}" ... />
What you need to do, is very close to what you're already doing. First, define a class named Resources.cs with following content
public class Resources
{
private static AppResources resources = new AppResources();
public AppResources LocalizedStrings
{
get
{
return resources;
}
}
}
This allows us to create a instance of your Resource File in XAML. To do this, open App.xaml and add following
<Application.Resources>
<local:Resources x:Key="Resources" />
</Application.Resources>
Now when you need to do bindings in your XAML, you do it like this:
<Button Content="{Binding LocalizedStrings.MainButtonText,
Source={StaticResource Resources}}" />
What you'll notice is that it doesn't work in Blend, yet. To make it work in Expression Blend,
add the following file: DesignTimeResources.xaml in the Properties Folder, and add following content
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:YourNameSpace">
<local:Resources x:Key="Resources" />
</ResourceDictionary>
Now, you press F6 in Visual Studio to recompile, and voila, your localized strings are available in Expression Blend!
A real-world example from one of my projects:
AppResources.cs
DesignTimeResources.xaml
App.xaml
I'm trying to create an Eclipse plugin to support a proprietary project file format. My goal is to be able to drag and drop a file in the Project Explorer (any type of file) onto a file of the type I support, and have the name of the file being dragged appended to the end of the proprietary file.
Right now, I have a custom editor that can parse out some data from an existing file in a manageable way. This means that I have an editor associated with the file type, such that my special icon shows up next to it. I don't know if that's relevant.
I'm attempting to use the extension point "org.eclipse.ui.dropActions" but I'm not sure how to register my DropActionDelegate (implements org.eclipse.ui.part.IDropActionDelegate) such that it will be called when a file is dropped onto one of my type within the Project Explorer.
Anybody have any ideas? Am I even on the right track with the DropActionDelegate?
You are on the right track implementing an IDropActionDelegate:
class DropActionDelegate implements IDropActionDelegate {
#Override
public boolean run(Object source, Object target) {
String transferredData (String) target; // whatever type is needed
return true; // if drop successful
}
}
The purpose of the extension point org.eclipse.ui.dropActions is to provide drop behaviour to views which you don't have defined yourself (like the Project Explorer).
You register the drop action extension like this:
<extension point="org.eclipse.ui.dropActions">
<action
id="my_drop_action"
class="com.xyz.DropActionDelegate">
</action>
</extension>
Don't forget to attach an adequate listener to your editor in your plugin code:
class DragListener implements DragSourceListener {
#Override
public void dragStart(DragSourceEvent event) {
}
#Override
public void dragSetData(DragSourceEvent event) {
PluginTransferData p;
p = new PluginTransferData(
"my_drop_action", // must be id of registered drop action
"some_data" // may be of arbitrary type
);
event.data = p;
}
#Override
public void dragFinished(DragSourceEvent event) {
}
}
