I've tried a few different ways to implement tooltips support for a list component in a form. Following is code that I think should be close but it does not work.
The code is placed in the initialization script for the list component in a simple form and the list is the only component in the form.
My workaround is to display what would be the contents of the tooltip in static text below the listbox and change the static text as the selection in the list changes. I have this working but it's not the best way to present the information.
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;
ToolTipManager.sharedInstance().registerComponent(configurationObject);
configurationObject.addMouseMotionListener(new MouseMotionAdapter()
{
#Override
public void mouseMoved(MouseEvent e) {
JList<?> l = (JList<?>) e.getSource();
Integer i = l.locationToIndex(e.getPoint());
ListModel<?> m = (ListModel<?>) l.getModel();
if (i >= 0) {
String item = m.getElementAt(i).toString() + i.toString();
l.setToolTipText(item);
}
}
});
I believe I could do this by subclassing the list and overriding getToolTipText but I'm not sure how to do this in install4j.

I have created a plugin,Where I have a multi page editor with two pages.
Page1- Source Code Editor.
Page2- For Manipulation.
My problem is if there is any compilation error in the code the second page must display another content like "Error".
Otherwise it will show my manipulation form.
For that I need to fill the composite with diffrent content each time the pageChanges. But it doesnt work.
How can achieve the scenario. While clicking the second page the content must be recreated or refreshed for the new content
public void createPage1(){
intializePage1Composite();
updatePage1Content(this.page1Compostie);
int index = addPage(this.page1Compostie);
setPageText(index, "Service Behaviors ");
}
public void updatePage1Content(Composite composite){
boolean error=getPageStatus();
if(!error){
/**
*Content of Normal Page
*/
}
/**
* setting the page to error
*/
else{
/**
*Content of Error Page
*/
}
}
protected void pageChange(int newPageIndex) {
super.pageChange(newPageIndex);
if (newPageIndex == 1) {
updatePage1Content(this.page1Compostie);
this.page1Compostie.redraw();
}
}
Any advice ?
To replace all the children of a composite you first call dispose() on each existing child control. Next add the new controls. Finally call
composite.layout(true, true);
on the parent composite to force it to update the layout.
If you just want to switch between two sets of controls you can use the GridData.exclude flag and Control.setVisible to include/exclude controls. Again call layout at the end.
DevExpress builds combo boxes in a very odd way. The standard identification built in to Selenuim and Watir (including Page Objects) does not see it as a Select List.
So how can you automate these successfully?
So as it turns out, DevExpress builds combo boxes as a text box with several layered tables associated with it but not under the text box in the HTML tree.
interactions are all done via embedded scripts.
I found the simplest way to automate this object is to identify the text box and the lowest table containing the list of items (3rd table down).
for example (using Watir and Page Objects)
table(:list,:id => 'ComboBoxValue_DDD_L_LBT')
text_field(:state, :id => 'ComboBoxValue_I') #:name => 'State')
I have not found a way to get better IDs at these levels, but we are working that issue.
Then your select code looks like this:
self.state_element.click
row = list_element.find { |row| row[0].text == value }
row.click
Note that with Selenium, you can execute arbitrary javascript in the client to query and set the control's state (if the client-side is enabled for the control). Here's how I did so to extract (and set) the selected text from a combobox named localeSelectList:
// unit test code, c#
[TestMethod]
public void SomeTestMethod()
{
IWebDriver ff = new FirefoxDriver();
ff.Navigate().GoToUrl(homeUrl);
// find the element as an iWebElement
IWebElement localeBox = ff.FindElement(By.CssSelector("#localeSelectList"));
Assert.IsTrue(localeBox.Enabled);
// get the text from the control via javascript
var locale = Util.GetControlText(ff, localeSelectList);
Assert.IsTrue(locale == "English");
// set the text in the control via javascript
Util.SetControlText(ff, localeSelectList, "German");
// verify the text was set
locale = Util.GetControlText(ff, localeSelectList);
Assert.IsTrue(locale == "German");
}
// helper methods, Util class
static public string GetControlText(IWebDriver driver, string controlName)
{
string script = string.Format("return {0}.GetText();", controlName);
var controlText = ((IJavaScriptExecutor)driver).ExecuteScript(script);
return controlText.ToString();
}
static public void SetControlText(IWebDriver driver, string controlName, string controlText)
{
string script = string.Format("{0}.SetValue('{1}');", controlName, controlText);
((IJavaScriptExecutor)driver).ExecuteScript(script);
}
It's not quite the same thing as interacting with the extensions via primitives (clicks, keystrokes, etc) as it won't fire the event handlers for these events, but if your extension uses 'valueChanged' events instead of primitive handlers it's pretty close to the same.
Also note: you can use client-side javascript to find and return elements using jquery/css selectors and ids, as follows:
IWebElement element = (IWebElement) ((IJavaScriptExecutor)driver).ExecuteScript("return $('#.myElementId');")
That's right with several layered tables, but I would like to add that they are only visible when combobox is clicked. First
var cmbParameterGruppen = webDriver.FindElement(By.Id("phContent_ParameterGruppenComboBox_I"));
cmbParameterGruppen.Click();
and then
var tblItems = webDriver.FindElement(By.Id("phContent_ParameterGruppenComboBox_DDD_L_LBT"));
var parameterGruppen = tblItems.FindElements(By.XPath(".//*"));
var count = parameterGruppen.Count;
Debug.WriteLine($"Count = {count}");
if(count > 0)
parameterGruppen[count - 1].Click();
I select hier last row.
I need to develop a control which is similar to the Nested Grid in the Smart GWT.
User will be having a column for expansion images, when user clicking on the image in a particular row, a sub grid has to be opened there itself. Here all remaining rows needs to move down.
How can i achieve that functionality? Can anybody give me some clues so that i can proceed.
I have already a grid which is a celltable with custom header(with search functionality implemented).
Thanks,
Saritha.
Create your nested widget (myNestedWidget) that you want to show. It should have a CSS style "position: absolute", unless your grid is added to the LayoutPanel (or similar), in which case you can position your widget directly. Let's call the parent widget of your grid gridParentWidget.
In your CellTable add the following handler:
myTable.addCellPreviewHandler(new Handler<myObject>() {
#Override
public void onCellPreview(CellPreviewEvent<myObject> event) {
if ("click".equals(event.getNativeEvent().getType())) {
if (event.getColumn() == 0) {
int top = myTable.getRowElement(event.getIndex()).getAbsoluteBottom();
int left = myTable.getRowElement(event.getIndex()).getAbsoluteLeft();
myNestedWidget.getElement().getStyle().setTop(top, Unit.PX);
myNestedWidget.getElement().getStyle().setLeft(left, Unit.PX);
gridParentWidget.add(myNestedWidget);
Scheduler.get().scheduleDeferred(new ScheduledCommand() {
#Override
public void execute() {
int height = myNestedWidget.getOffsetHeight();
myTable.getRowElement(event.getIndex()).getStyle().setHeight(height + "px");
]
});
}
}
});
}
This is obviously an outline of the solution. The details of the implementation may vary slightly depending on which widgets you use for your parent widget and your nested widget. If you change z-indexes somewhere, you have to take it into account too. You also need to make sure that your nested widget fits into the width of your grid, or you'll need to wrap it in a ScrollPanel and set a width to it explicitly.
I'm using the DockPanel Suite by Weifen Luo in a little project (webbrowser) and have managed to be able to create tabs and navigate the webbrowser element inside each tab.
But how am I able to change the tabs title/name when the page is navigating to another site?
Basically I just need to get into the current tabs form.
You can get the current tab by using DockPanel's ActiveContent method. For example:
Form myForm = myDockPanel.ActiveContent();
myForm.TabText = "Stack Overflow";
DockPanel.ActiveDocument and DockPanel.ActivePane can also be useful.
After having worked on this a few weeks (not 'till now though :P) I have to say, that this is currently not possible.
You can manage your own (assuming your Document Form is a specific class) by managing:
'FormClosing' and 'Activated' events
'Activated' set your own "active" document to 'this'.
'FormClosing' set your own "active" document to null.
FormClosing is just to catch the case where you are closing the last document. Activated is what manages everything else, like when a new document gets created and is made the active window, etc.
You can use a static global to manage focus. Then access it from anywhere else:
public partial class MyDocument : DockContent
{
public static MyDocument ActiveDocument { get; private set; }
I needed the ability to check which document was active, and set that document to active again after changing some UI elements that automatically reset the active tab, so I used some pieces from here and the DockPanel FAQ, and did some digging to figure out the answer to this problem:
public string GetActive()
{ //Verify if forms that dock in main window are already open
foreach (DockContent form in dockMain.Contents)
{
if (form.DockHandler.Pane.ActiveContent.DockHandler.Form.Name.ToString() == form.Name.ToString())
{
string formName = form.Name.ToString();
return formName;
}
}
return null;
}
And then in some other method you will call:
string activeForm = GetActive();
I'm trying to create new GTK Notebook tabs that contain both a name (as a Label) and a close button (as a Button with an Image) with the following code:
Label headerLabel = new Label();
headerLabel.Text = "Header";
HBox headerBox = new HBox();
Button closeBtn = new Button();
Image closeImg = new Image(Stock.Close, IconSize.Menu);
closeBtn.Image = closeImg;
closeBtn.Relief = ReliefStyle.None;
headerBox.Add(headerLabel);
headerBox.Add(closeBtn);
headerBox.ShowAll();
MyNotebook.AppendPage(childWidget, headerBox);
This seems to work just fine; however, the button is about 1.5 - 2 times the size is needs to be, so there is a lot of extra space around the image inside the button. Having looked at remove inner border on gtk.Button I now see that the culprit is the "inner-border" style property of the GtkButton, but (being new to GTK) I can't seem to figure out how to override its value.
Is there some method of doing this that I'm missing? I don't have any reservations about not using a Button/Image combination, so any more obvious suggestions are welcome.
Note: I have seen the suggestion in the linked question to use an EventBox, but I was not able to add the Relief and mouseover effects to that Widget.
You are in luck. I just made the exact same thing yesterday, and can fortunately give you some code. The trick is to create a Custom Tab Widget.
public class MultiTab : Gtk.Box
{
public Gtk.Label Caption;
Gtk.Image img = new Gtk.Image(Platform.IMG + "tab_close.ico");
public Gtk.ToolButton Close;
public Gtk.Notebook _parent;
public MultiTab ( string name )
{
CreateUI(name);
}
public MultiTab(string name, Gtk.Notebook parent)
{
_parent = parent;
CreateUI(name);
CreateHandlers();
}
void CreateUI(string name)
{
Caption = new Gtk.Label(name);
Close = new Gtk.ToolButton(img,"");
PackStart( Caption );
PackStart( Close );
ShowAll();
Close.Hide();
}
void CreateHandlers()
{
Close.Clicked += delegate {
_parent.RemovePage(_parent.CurrentPage);
};
}
public bool Active;
}
Next all you have to do is use this widget(or a similar one created by you) in Gtk.Notebook like this:
MyNoteBook.AppendPage(new <YourPage>(), new MultiTab("<your caption>",this));
And You're done.
Here is a screenshot:
Add this:
RcStyle rcStyle = new RcStyle ();
rcStyle.Xthickness = 0;
rcStyle.Ythickness = 0;
closeBtn.ModifyStyle (rcStyle);
Add items to box using Gtk.Box.PackStart/PackEnd methods rather than generic Gtk.Container.Add method. PackStart/PackEnd will allow you control how child widgets will be allocated space:
headerBox.PackStart (headerLabel, true, true, 0);
headerBox.PackEnd (closeBtn, false, false, 0);
