First of all thanks for all the previous advice.
I have come across a rather tricky little problem.
I have a string which I want to display into a Label, normally no problem, but the string is longer than the label will allow. However the similar problem with the text box was resolved with the use of the swt awt hybrid. What I would like to do is replicate this with the label.
Is there way around this? or would the workaround be to have the text area to settext to desired text and then to set the text enable to false so it is grey text.
Could anybody advise?
Your workaround to use Text is perfectly fine. You can mimic label behavior by setting appropriate background color and font and disable it. Also such "labels" are able to provide copy functionality, which is not possible for usual Labels.
Another workaround would be to calculate bounds of your String by using FontMetrics and then cut the string in the end with "..." and providing a tooltip with a full Sting length.
It is also possible to use SWT.WRAP constant for labels, thou it will be still restricted by the width of the Label.

I try to migrate our custom plugins from TinyMCE 3 to 4.
In some cases there is some text in the plugin's window to describe how to use it.
Fiddle example: http://fiddle.tinymce.com/Hndaab/1
So if the text is very long, the window width increases until some parts are out of the viewport.
How can i tell the WindowManager to use automatic word wrapping for my labels?
I already tried to define a width for the window. And in another plugin i found a param "multiline". Both didn't solve my problem.
Any ideas? Thank you
I've been trying to accomplish something similar for mobile commpability where the windows are to large for the viewport and so far the closest i've gotten is to set the css for .mce-window to
.mce-window {... max-width:100%;max-height:100%;}
maybe that will be enought to fix your specific problem, even if I still have some ways to go for it to fluidly only fill out the available viewport space on all other windows.
I have a combo box that when I open it should show text like
However I get something like
with the scrollbar set to middle. Thing is sometimes for the same values it shows properly
and sometimes it shows from middle(for same value).
I want it to show properly like in the first image and I've tried a couple of things but with no succes.
itemSection.setHoverAlign(Alignment.LEFT);
itemSection.setTextAlign(Alignment.LEFT);
itemSection.setAlign(Alignment.LEFT);
... and other irelevand stuff ...
Any help is highly appreciated. Thanks alot!
If I am not getting wrong, You want to set your scrollbar at particular position. FOr that you need to ovverride the css of that and try to set scrollbar position to 0. So that your problem will get solved.
The problem with any kind of selections box is, that the boxes display and behave completely different across browsers. The older the browser the worse it handles long texts in selection boxes (some just truncate the text). I suggest to keep the displayed text as short as possible. That way you can avoid this problem.
If you really need long description, you can try to add a tooltip to every entry. Or use a different widget to make the select from, e.g. some custom widget in a separate dialog...
This sounds like a pretty simple thing to do but I havent been able to find an easy way to do this. How do I create a panel with a title and a border which can contain my widgets? I have seen the SectionStack class which provides this. But I dont want to create a section stack.
Window can be added to a layout and drawn. But is it the only way or is there a container class that I am missing?
Also, how does one center things? Say a textfield and a button at the center of the page. How is this achieved?
If you are using a DynamicForm, you can give it a border and title with
form.setIsGroup(true);
form.setGroupTitle(title);
This actually works for Canvas, too (which is the superclass of most widgets and layouts in SmartGWT).
(I just had the same problem, and found this question, as well as the thread Is there a "titled Border" on the SmartGWT Forums, which gave this answer. I tried and it seems to work.)
To do form-related tasks, look into DynamicForm. To set the inputs in the form, you use setItems(Item...). A text field is a TextItem. You set it's title to control the label that SmartGWT will build. To get a title for the form, the best I've come up with is to use a container canvas that will contain both the title (probably a Label element) and the DynamicForm. To center the inputs, I believe you'd need to use setAlignment on the DynamicForm.
You could create an object that is actually a VLayout that contains a Label (the tile), has a border as you need and includes a Canvas (the generic stuff you want included).
In my experience, I noticed that very often I have a DynamicForm visible, so I just add a BlurbItem control to diplay the tile and a small explanation.
I have spent a few days trying to get around the limitations with UITextField, namely no text wrap and number of lines. I have created a UILabel, which is used to display the text entered in UITextField and does all the formatting stuff properly. The UITextField is hidden and the user sees all the text entered only in UILabel as it's being entered.
Everything is working perfectly except for the lack of a cursor on the UILabel to show the user where the next character typed into the field will show up.
I have experimented with using various characters as cursors on the label. But there is no getting around the fact that it is not the standard blinking cursor indicator on the iPhone and so the whole thing just looks wrong.
Before I abandon ship and go for a UITextView (with its own set of issues) I was wondering if anyone has any ideas as to how a blinking cursor can be added to the text field on a label text.
Thanks in advance.
Your approach has other issues which make it worth rethinking the strategy.
How does selection look like?
copy + paste?
Do you handle right to left languages?
Auto correction?
The list is certainly longer, but I think it's enough to consider other solutions. But I agree that all of UIKit's text handling is a bit poor.
If you don't need to support selection, copy and paste, and only need multiline input, you could use a | character and animate it as if it were blinking... either that or perhaps a custom overlay view on top of the label, that would implement the cursor drawing, animation and positioning based on the length of the string and the font used.
– sizeWithFont:forWidth:lineBreakMode:
– sizeWithFont:constrainedToSize:
– sizeWithFont:constrainedToSize:lineBreakMode:
– sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode:
may help to achieve just that.
So what are the issues preventing you from going to a UITextView? It seems possibly easier to address those.
I'm developing an application for the iPhone where some text is shown in a UITextView. I want to search for a specific word in the text and then show the text with that specific word colored. If anyone can help me solve this, I'll be very glad.
UITextView does not allow any formatting of the text within it. If the text is static (i.e. doesn't need to be edited), use a UIWebView instead; that will allow you to apply HTML formatting.
If a web view isn't an option, your best bet will be to try to calculate where the text in question will fall in the text view and then draw some sort of highlight around it. NSString has some methods to calculate how much space you need to draw a given string on screen; by being very, very clever with those methods, you may be able to work out where the word you're trying to highlight is. Unfortunately, this will not be at all simple.
If you do come up with a solution, everyone here would probably love to hear about it!
