Dynamically increase the size of jtextarea so it can display added content

I want to know if ever there is a way to dynamically resize a jtextarea so that it shows the text that spans beyond its length. I want to display my service activity which grows in size and fills up the textarea, but after that i can't see what is being displayed as textarea size (maybe # rows) can't be changed dynamically once it is initialized. I guess the notion of document length and the rows are different. Rows doesn't mean a single line of text it seems. I want to know a solution or a workaround. Also can I reallocate the textarea if i can somehow find when my no of lines exceeds the area size.
This is kinda urgent as I am working on my thesis.
Thanks,
Akshay

This is kinda urgent as I am working on my thesis. You mean we are working on your thesis.
You could try use a DocumentListener. An event is fired every time a change is made to the Document. Then you could use the getPreferredSize of the textPane and compare it to the size of the textArea and make adjustments as required.
Actually, if you just add the textArea directly to the contentPane I believe it will grow automatically assuming the frame is large enough to allow it to grow.

I'm also not sure, but think I am lol, that if I were to pay the $27.99 if that applies to my iPhone and my iPad ? Or would that have to be two payments?

How to increase the size (Length and width) of check box

Hi All,
I have to increase the size of ( width and length) of check box, I have revised to check box topic in dev guide but didnt find any clue, i have also tried to use CCStyle class but that is also not working, I would appreciate if some can help me out on this. Thanks in advance , let me know if any clarification required.
Thanks
Pratap

Hi Pratap ,
I honestly don't know how to increase the size
But i am giving you an alternate solution : we can create two Images with check box type 1 ) with checked
2 ) with unchecked . ( you can create image of any size ) and get them displayed on OAF screen dynamically using switcher case .
Dynamically displaying image will give the illusion of check box being checked and unchecked .
keep this image moved to following media directory
eg : /oraapp/mfgtestcomn/java/oracle/apps/media .
Implement the switcher case , add the fire action to this Image Column , create a transient attribute and attach to this
column . Depending on the value returned by transient attribute display the image on the column .
Let me know if its not clear .

Increase the size of textview

Hi all,
I was trying to increase the size of a dynamically created textview.Is it possible to set the width of a textview in webdynpro?
Thanks
Kukku

Hi,
Try this code:
IWDTextView txtView = (IWDTextView)view.createElement(IWDTextView.class, "text_view");
       txtView.setWidth("Your_Desired_width");
       txtView.setDesign(WDTextViewDesign.HEADER3);
If you already have the text view created then you can get that particulat textview and can use the same API's, Use this code:
IWDTextView txtView = (IWDTextView)view.getElement("NAME_OF_YOUR_TEXT_VIEW");
       txtView.setWidth("Your_Desired_width");
       txtView.setDesign(WDTextViewDesign.HEADER3);
This will solve your issue. Please revert back incase you want any further assistance.
Thanks and Regards

Increasing the size of the SGA

I'm using the Oracle Enterprise Manager Database Control on a 10.2.0.4 instance running on Redhat Enterprise Linux. One of the recommendations that the AWR\ADDM always seems to give is: "Increase the size of the SGA by setting the parameter SGA_TARGET to N". I've gone through the process twice already by upping the SGA_MAX_SIZE and SGA_TARGET parameters. It's currently recommending to up it to 6176M, I have not done this yet.
(1) Is this one of the recommendations that you would ignore within the DBCA if performance of the database seemed acceptable?
(2) Why does it always come back from the AWR\ADDM as a recommendation?
(3) What SQL or performance statistics does it do to determine whether the SGA is undersized and how does Oracle determine the SGA recommended size that shows up in the ADDM feedback?
Thanks in advance...

Truely new questions do deserve new threads. Questions that are a direct result of responses to the initial question should be asked on the same thread.
If there has been a time gap between the last post on the initial thread and the new question coming to mind then a new thread is probably the better choice.
To answer the question asked if the database is not suffering ORA-04031 errors and performance is OK then I would ignore the recommendation to increase the size of the SGA yet again.
What you might want to do first is reivew how the sga is being used (v$sgastat) and look for bad code technique that leads to needing memory, i.e., the use of SQL that passes constants to Oracle in what would otherwise be the same SQL statement if a bind variable was used and excessive use of Dynamic SQL when again bind variables could have been used in the SQL.

PS Are you working on a version for the iPad and iPhone with Add Blocker? That would be great!

How do I increase the size of the text on the toolbar?

How do I increase the size of the toolbar text, please? For some reason, it's now very tiny, and everything I do only increases the font size of whichever web sites I access (which is not what I'm wanting to accomplish).
Thanks in advance for any help in this. Actually, I'm wondering what I might have done that would make the toolbar so tiny?

Do you mean the menu bar at the very top of your screen?
If so, open System Preferences > Displays > Display > Scaled
Try a different resolution.

How can I set timings to increase the size of an image in a Keynote presentation?

I know how to use inspector to bring in and fade out text boxes, but at the end of a slide I have a graphic (that is at the bottom of the slide during the rest of the slide) that I want to increase the size of to take up the entire slide. How can I do this?
Thanks

Welcome to Apple Support Communities.
The effect you're looking for is 'Scale'
In Keynote '09, 5.1.1 select the graphic.
Click Inspector in the tool bar, Build Inspector (3rd icon from the left), (Build In and Build Out are both set to None for this step) Effect, Action, and then Scale.
It rescales ('zooms') the selected item (image) up or down from 0% to 200%
Clicking on the More Options button at the bottom opens a drawer to the left, and gives you more control over how the build occurs, whether they happen automatically, timed, or when you click, and re-order build steps.
At 200%, double the original size, resolution could be a problem. There is a workaround, because it also scales smaller, down to 0%. So I would scale the graphic down 'small' as the first step to fit at the bottom, (even hide it behind a background-colored box) as you scale it down, and then at the end, scale up to full size to fill the screen at 'normal' resolution.
In the attached example, I use a 'scale' up to go from 100% to 130% on a map, and use arrows and a flashing line to point out the road where a specific business is located with 12 steps. Some elements in my slides have been intentionally obscured. For simplicity, I've eliminated showing any steps but the initial title and the scale.

How to increase the size of text boxes in FCPX without stretching the text inside?

How to increase the size of text boxes in FCPX without stretching the text inside?

There are two basic Title formats — I should say Layouts — available: Text (plain) and Paragraph. (The plain text version usually does not appear with the blue dot controls — those generally appear for the paragraph type control.)
If the Title is using a Paragraph layout, it's like having a mini version of Text Edit available inside FCPX. You can tell when you click on the text (when the title is selected) -- a rectangle will appear around the text like so:
double clicking on the text will give you the bounds controls which you can use to redefine the text area without distorting the text. Once selected, notice the button that appears in the top right corner of the canvas:
Pressing that will activate the ruler. You can right click on the ruler and add Tab Stops (left, right, center and decimal.)
So if the title uses paragraph formatting, you can create a very WYSIWYG type of display text (use the Text inspector to alter text selections within the paragraph bounds.)

How to increase the size of piechart in ssrs?

Hi how to increase the size of piechart in my design mode its showing very large one,when running/preview mode its displaying very small, i have total 10 values to dispaly in the legend series values,So here i have set the visibulity option to out side ,
so if the pie chart is dispalying small ,the values of the legend will come in one place and ,so can you suggest me how to increase the size of my chart and how would i show my legend values separatly without closing one by one.
Can some one please help me out for this..

Hi Ychinnari,
According to your description that you want increase the size of pie chart in the design mode to make all the ten values in the legend series to display, you have do some setting but the pie chart still display very small and not display some of the
values, right?
I have tested on my local environment and found that the display of the chart legend value can be effect by many factor: the size of the chart, chart area position and chart legend position.
Details steps below for your reference about how to set the properties to make all the legend values display correctly:
Select the Chart properties and expand the size and increase the values for the width and the height, then preview to see if all the legend values are display.
If this do little help, the problem due to the chart area position and chart legend position need to reset too.
Select the chart area properties and expand the CustomPosition under the Position, choose the Enabled to true and reset the Width, height of the pie chart.
Reset this properties to make the chart area more Narrow, thus we can set the Legend area more wider.
Select the chart Legend properties and expand the CustomPosition under the Position, choose the Enabled to true to reset the Width, height of the chart Legend
Reset this properties to make the Legend area more bigger (wider and higher) thus it will display more values in the Legend area.
If your problem still exists, please feel free to ask.
