While I am aware that set_placeholder_text("I am the placeholder") will solve my problem, this feature is only available from Gtk+ 3.2 onwards.
I would like to know the simplest method to remove the default text from a Text Entry box when the user clicks on it.
Using the 'focus-in-event' signal is a satisfactory solution here.
In the callback, set the text in the Text Entry box to "" so that it is cleared when clicked on (i.e., when the Text Entry box gets focus).

I am new to Unreal Engine. Currently I am learning UE5.
I am trying to change text and I had run into problem. And somehow I can't find any information about it.
I simply created user widget, I put a button and a text block. So the question is how can I change text in text block using onclick button event?
I found the solution. It was easier than I thought.
First mark your text as variable. Then literally [Get] it in ur bp.
Get a branch [set 'name'] from your text (I my case Head Txt).
Then from Set set a branch [SetText] and type ur text.
That's it!
Can't believe I spent so many time trying to find the solution in blueprint videos, but accidently found out how to do this from C++ code.
Additional note to this
For beginners, sometimes SetText will not show due to "Context Sensitive" is ticked (by default)
So you need to uncheck the box and make sure to select correct type of SetText with correct target widget type.
I am trying to build a small GTK 4 app where the user inputs some data, the program does some computations, and it outputs results in a tabular format.
Currently, I have implemented this using a GtkGrid with Label objects showing the results. This works, but a major downside is that the text is not selectable by the user.
Is there a standard Gtk interface for outputting static, selectable text or tables? For example, in the Firefox (whose Linux version is based on GTK) settings page, you can use the cursor to select all the explanatory text.
Searching for "text" in the GTK documentation brings me to the Text Widget Overview page, which is all about multiline text editing. But I don't want my output to be editable—I just want the user to be able to highlight the text and paste it somewhere else if they want.
GtkLabel has a "selectable" property which does just that. It's also mentioned in a separate section of the GtkLabel docs
Microsoft word fails to add hyperlink over bookmark and show Hyperlink text everytime
I select the text.
Then i add bookmark from Insert -> link -> add
Then when i add Link (ctrl+K) and go to insert document and screentip by clicking bookmark
It just show this text instead of original text.
Can anyone suggest what the issue is actually?
I think this is off-topic but you have more experience here than I do.
Press Alt+F9 to toggle display of field codes / results.
On some computers, this is Fn+Alt+F9. On Macs, use Opt instead of Alt.
The original text does not appear in the field code but is there and will show up in the document.
I originally missed your real question and the mistaken answer follows below.
This has nothing to do with the presence or absence of the bookmark.
This is the ordinary behavior of the Hyperlink and the AutoText fields in Word. The text displayed in the document does not appear when you display the field.
This is examined in my article on the Microsoft site about Pop-Up text in Word.
Here is the field insertion dialog box:
Here is what it looks like in the document:
And here is the field code shown using Alt+F9:
Note that the display text is not shown at all in the field code. It is still there. If you select the field and enter the following in the Immediate Window of the vba editor you will see the display text.
? Selection.Fields(1).Result
I suspect this comes from the origination of these two fields. With the hyperlink field, it is often created using selected text. It does not especially make sense, but it is how the field operates.
I just started working on an eclipse RCP application in my company and search now for following component:
In the eclipse preference dialog is a text input field with a eraser which clears the text box (see image).
Is there a component in eclipse RCP which does exactly that? Or one where I can set an image in a text input field, so I can implement just the functionality.
Or have I to write my own component extending from Text?
Thanks.
Eclipse does not offer such a component, so you will have to implement one yourself.
But I wouldn't extend Text for this. Simply create a Composite with SWT.BORDER style, and a Text and Button as children. If you don't give the Text a border, it looks like the button is within the text box. Instead of the Button you could use a ToolBar with a single ToolItem, both with the SWT.FLAT style. This will look much better than a regular button.
Text text = new Text(parent, SWT.SEARCH | SWT.ICON_CANCEL);
This is present in Luna's API, don't know about older versions. You can check more here: http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet309.java?view=co
I have a weird behaviour that has only shown up in the last week. I don't use IB, all the controls are created in code.
I have a text field with a keyboard active. The first time I load the text field and use the keyboard, everything works normally. The second time I use it, the typed text does not show in the text field. However, the text is in the text field programmatically. For example, I can use it to execute a search. When the keyboard closes, the text appears.
Some of my UITextFields have misaligned text. For example, I write "hello", and instead of displaying centered inside the field like normal, it displays shifted several pixels downward to the extent that the bottom of the text is cut off. It's almost as if another view is chopping the bottom off the text by obscuring it.
I use three20, but according to http://groups.google.com/group/three20/browse_thread/thread/d7c4bc1ee2f9590d#, Xcode is suspected of causing the problem. I seen the behavior on 2 diferent macs, one running with Snow Leopard (10.6) and the other with Leopard (10.5).
This is how the problem looks in Xcode:
It is not obvious, but there is text in that search field. Notice that the placeholder text is not show. However, if I hit Search, the code executes with the entered text.
This is how the app appears in the simulator:
I finally find the reason.
I call [textField becomeFirstResponder] in a function called from loadView. But I move it to viewDidAppear and everything work Ok...
I've seen that happen with text fields and affine transforms. If you rotate a text field using a transform, the text shows up in a seemingly random part of the superview. If you use a transform to move the text field to make room for the keyboard, you might be seperating the embedded text editor from the field itself. That would also explain why the text is in the code because the text attribute of the text field is not affected by the visual layout of the UI.
