How do you go about creating a JTextfield with a drop down embedded into it? So you can use the drop down to select a value which will show up in the JTextfield. I am not looking for autocomplete but the ability to select and show values from combobox in the same textfield. For example a browser's url box and it can also act as a drop down showing urls that match it. I would like the drop down button to show up however.
If there is no specific reason of why you want to use JTextField, I suggest you to use an editable JComboBox. It is a combobox that you can type customized text on the top option field and also you have the ability of selecting the customized text and process it from combobox. Take a look at this example, it might be the solution that you are looking for: Editable ComboBox with Java

Sample ComboBox
Is there a way to create a combobox like the one shown in the mockup above? One where I can search/filter within the dropdown itself (red text in image), where the column headers would normally go (if enabled). I've been asked to create this specifically in our access database, and I'm not sure if it's possible. If this is possible, what combobox properties would need to be changed to make it happen?
I have a MS Access form that is bound to a query in the database. I added a textbox and added a row source to a Hyperlink datafield in the query. When I open the form, it won't allow me to drop a file into the textbox.
Here's the deal. When I follow this EXACT same process on a new form, it works perfectly. That is, I open a blank form and I bind the form to some new query, let's say qryNewIdeas. Then on the blank form i add a textbox, let's say Text0. Then, when I select Text0, I go to the data tab - row source and choose the dropdown arrow to select the hyperlink field, lets say NewIdeasAddress. I click SAVE and open the form. It works PERFECTLY.
BUT, when I repeat this on an existing form (the one where I need the thing to actually work), it does nothing. It adds and changes the textbox to a hyperlink box (I note this because of the blue underlined word that appears in the box). But it won't allow me to drop files to this location.
I tried commenting out ALL of my VBA code to try to make sure that something wasn't hindering it (say in an OnLoad event) AND I've checked all of the form and control box properties and they seem to be the same in both the existing form and the test form.
I can't determine why it works on one form and not the other; Solution needed.
If you have access to "the data tab - row source ..", you are in design view.
When you later open the form, you are in form view, a completely different animal which specifically prohibits design changes.
It sounds like you will have to rethink your concept.
I want to show a placeholder in a ComboBox if no values has yet been selected or the previously selected one has been removed / deselected. For single-column ComboBoxes that works like a charm using #;"My placeholder" as the Format of the ComboBox. So far so good.
The problem starts if my ComboBox has more than one column. How can you set the placeholder value for a multi-column ComboBox? More general: How can you specify the Format for a multi-column ComboBox?
Is it for example possible to color the first column green and the second one red? And if it is possible, please tell me how.
I could not find any specification on how to set the format for multiple columns. Neither on MSDN nor on support.office.com.
P.S.: I do not care if a working solution relies on VBA or if it can achieved just by entering something in the layout or design view.
Sounds like you are outgrowing what a ComboBox can easily provide in Access.
First, combo options, and then my real suggestion.
Here are your ComboBox options:
Try conditional formatting, and see if you can get the combo's text box to change color if the value is null.
You could make a UNION query that appends your placeholder record to the top of your Combo's real recordsource
You could try to get your users used to the idea of 'blank' = null, and fix it with training.
I have never seen a way to do different combo column colors in Access.
My REAL suggestion:
Ditch the combo and go with a modal dialog form that pops up for the user. This will let you format everything much more closely to what you want.
You can put textboxes on your main form to display the placeholders.
The user clicks on the textbox to open your dialog form.
Creating combo boxes in Access is easily enough. However, drop-down lists are slightly easier for users when there's no need to edit or add values to the list.
Is there a property I can set to make a combo box control manifest as a drop-down list? Is there a custom ActiveX control available with drop-down style?
See whether the combo box .Dropdown method gets you close to what you need. I cribbed this example from the Access help topic:
Private Sub SupplierID_GotFocus()
Me!SupplierID.Dropdown
End Sub
If I am understanding your phrase "manifest as a drop-down" correctly, I think you mean that you want to restrict the user to selecting from a set of pre-populated options only.
Provide a List of Approved Values to Select
For example, if you want them to select a Month, and there are only twelve valid entries Jan-Dec, you can provide a list of months from a query, table, or direct input into the Combo Box's Row Source property.
Keep the User from Adding New Values or Editing Existing Values
What I think you may mean by "manifesting as a List Box" is that you can also then restrict the user to only selecting from your provided values by setting the Limit to List property of the Combo Box to Yes. Setting this property will restrict your users to your list, and not allow edits or new list entries. Remember to take addition steps if you need to make sure the user has selected one of your list values.
Use Dropdown and an Event like On Got Focus together
The Dropdown method "opens" the list so that the user can see the available options. For example, you can set it to the control's On Got Focus Event property so that the user will see some or all available options when the focus is set to this control.
Best of luck!
I jus Want to know, how could be possible to create Dynamic Components in Flex run Time.
For eg: creating a combo box with change Handler Dynamically, text box Dynamically,
Now, the value of combo box and textbox should place in a VO Class and the VO class also to be created Dynamically,
user have to provide how many fields they need and wat are the components needed and according to tat Dynamic VO has to Create in run Time,
Hope This is clear,
kindly suggest me a Example, Thankxxx in Advance
To create Dynamic class is tricky.
As per your requirement you want some combo box with change Handler, text box, etc.
Once you know what component you have to display according to vo which is been created dynamically.
You can create One custom component which contains your all required component (i.e. combo box, , text box, etc. )
or
Can create different custom component. Selection is yours.
There should be one parameter/condition, which will decide which component should be displayed at run time. Like adding switch case or your own logic.
While creating combo box you can add addEventListner in actionscript to handle change even and can dispatch custom event or can perform your defined operation.
In the same way you can addEventlistner to your custom component (ex. – text box, checkbox, etc.).
There should be unique key for all if user want to create combo box unique key should be 1(sample/any dynamic value can be retrived from VO), text box unique key should be 2, etc…. it will help you while creating dynamic component.
Make sure while creating component you have to use concept of set and get method for passing parameter.
Create only required component by using proper Flex component life cycle.
Hope this may help you bit as rough understanding.. or can search for better approach..
