[news.eclipse.platform.swt] Re: Text Control Decorator in Cocoa

artem@xxxxxxx (Artem Redkin) — Sat, 04 Jul 2009 08:07:03 GMT

Hello,

Thank you, i will try that.

Apart from native call, is there any other way to do the same (draw a text field border) with standart SWT.Cocoa methods?

Hi,

If you really want the native drawing that HIThemeDrawFrame provides then
you'll need to create this native and call it.  SWT's OS class on Cocoa does
not contain it simply because the toolkit implementation does not use it.
It is a valid call to make from the Cocoa world, and SWT's OS class does not
provide a Cocoa equivalent.  Also, I believe that this function will be
supported on OSX going forward, unlike most of Carbon, so you shouldn't need
to worry about re-writing your use of it any time soon.

Hello.

I am trying to create a SWT.Cocoa version of a custom widget. With Carbon
(i also have version for win32 ang gtk), i used paint listener and on
paint event called OS.HIThemeDrawFrame (Carbon native call), wich draws
text field frame.
In case of Cocoa i found only OS.HIThemeDrawFocusRect, wich doesn't draw
text field border frame, only focus frame.

Is there any way to draw text frame with Cocoa?

Thanks in advance.

[news.eclipse.platform.swt] SWT Maven artifacts

jelle@xxxxxxx (Jelle) — Fri, 03 Jul 2009 22:49:18 GMT

Hello,

What is the status of 3.4 and 3.5 maven artifacts for SWT ?

I found the following post containing details on managing the various architectures, but this seems rather involved. http://blambi.blogspot.com/2007/07/maven2-swt-builds.html

And then there is this bug report
https://bugs.eclipse.org/bugs/show_bug.cgi?id=199302

I've tried building a pom.xml with architecture switching for 3.5 myself, but I don't (yet) know enough about maven to get this to work...

Any thoughts?

Best,
Jelle.

[news.eclipse.platform.swt] Floating Composite/Menu

daniel.rampanelli@xxxxxxx (Daniel Rampanelli) — Fri, 03 Jul 2009 13:09:07 GMT

Hi,

I'm trying to create an autocompletion/chooser mechanism for a Text widget. I should be able to input some search parameter into a Text field and then choose one of the possible "elements". This should look as a list of possible values underneath the field.

I've tried to create a Menu below the field and fill it up with the right items. This works and we can even navigate through the possible elements. BUT, unfortunately we can not type or modify the search parameter while we have the focus on the Menu (and I can't neither a way to listen to keyboard inputs in the Menu).

Another option would be to use a window (created with SWT.TOOL). To me it doesn't look to good (e.g. the window focus problem) and it looks like a lot of work.

If I would be able to use the Menu, it would be great!

Has anybody hints on how to solve my problem?

[news.eclipse.platform.swt] SWT Layout issue

saleem1209@xxxxxxx (Saleem ) — Fri, 03 Jul 2009 00:42:26 GMT

Hi Need help with this automatic layout refresh issues. I have a Composite which lays out well when the screen is instantiated for the first time and the user interacts with the screen without a problem. If the screen stays idle for say about 30-40 minutes the screen refreshes by itself and components get squashed and overlap each other making the screen unusable for users. Any idea whats causing this sort of behavior? Thanks in advance. Saleem

[news.eclipse.platform.swt] right aligned menuitem in menubar

jkeller1@xxxxxxx (Jan) — Thu, 02 Jul 2009 21:09:51 GMT

Hi,

is there any way to make a menubar in SWT where some menuitem are normal (left) aligned and then there is finally one item that is right aligned.

What I want is something like this:

menuBar = new Menu(mainShell, SWT.BAR);
MenuItem file = new MenuItem(menuBar, SWT.CASCADE);
MenuItem actions = new MenuItem(menuBar, SWT.CASCADE);
...
MenuItem turns = new MenuItem(menuBar, SWT.CASCADE);

But with alignment:
File Actions ................................... Turns

And Turns is on the right side of the window.

Regards,
Jan

[news.eclipse.platform.swt] Memory usage with text area, styled text and large files

berlin.brown@xxxxxxx (Berlin Brown) — Thu, 02 Jul 2009 19:44:07 GMT

I am loading large files (5,10,30MB) into a text area and also adding syntax highlighting.

The problem, if I hope a 5,10,30MB file, the memory heap usage goes 10 times the file that file that is loaded. So, a 5mb file will eat up 50MB of heap memory. And a 10MB file will normally crash the JVM so I have to increase boot heap memory parameters.

Is there a way to avoid this? I am loading the data as a string, that may be the issue. But, the string data memory is exactly the 5,10MB extra. It seems that whenever I use styled text is when I see the memory ramp up?

Here is very similar code to what I am doing. -------------- styledText.setText("123456789\r\nABCDEFGHI"); StyleRange styleRange1 = new StyleRange(); styleRange1.start = 2; styleRange1.length = 16; styleRange1.foreground = shell.getDisplay().getSystemColor(SWT.COLOR_BLUE); styleRange1.background = shell.getDisplay().getSystemColor(SWT.COLOR_YELLOW); styleRange1.fontStyle = SWT.BOLD; StyleRange styleRange2 = new StyleRange(); styleRange2.start = 14; styleRange2.length = 3; styleRange2.fontStyle = SWT.NORMAL; styleRange2.foreground = shell.getDisplay().getSystemColor(SWT.COLOR_YELLOW); styleRange2.background = shell.getDisplay().getSystemColor(SWT.COLOR_BLUE);
