99.1 Known Issues</h3> | |
<h4> | |
99.1.1 Available Colors on 8-bit Linux</h4> | |
Typically, in Gnome Linux installs running with 8 bitplain visuals (i.e. 256 color mode), before the | |
Eclipse application is started, you already do not have any free colors. This may mean that Eclipse | |
is unable to allocate the default widget background color causing it to display a white background. | |
The functionality, however, is not affected. | |
<h4> | |
99.1.2 XInitThreads and Linux</h4> | |
SWT makes use of the XInitThreads system function to allow graphics routines to | |
be invoked from non-user-interface threads. However, the implementation of XInitThreads | |
on Linux has several issues, which cause the following SWT problems: | |
<dl> | |
<dt><b>Printing Support</b></dt> | |
<dd>The X printing extension implementation on Linux currently does not work for applications | |
which are XInitThreads enabled. This makes it impossible for us to provide printing | |
support on Linux. Until this is rectified, <code>Printer.getPrinterList()</code> will | |
always return an empty array on the Linux platform.</dd> | |
<dt><b>Drag and Drop</b></dt> | |
<dd>On Motif, SWT only supports dragging between windows running on the same system process. | |
In particular, dragging a file between Eclipse and another application will cause the | |
drop target application to hang. This is a result of a bug in the Motif libraries for | |
applications that are running XInitThreads.</dd> | |
<dt><b>IME Support</b></dt> | |
<dd>The Japanese IME support provided by Linux is currently incompatible with applications | |
which are XInitThreads enabled, and will cause them to hang.</dd> | |
</dl> | |
<h4> | |
99.1.3 Disposing in a Focus Event</h4> | |
Applications should not dispose widgets in focus changing events. Doing so on Motif may cause Eclipse to terminate, | |
since Motif accesses the disposed widget within their internal focus change event handler. | |
Similar but less serious issues exist on Windows such that occasionally an SWT exception can be thrown. | |
<h4> | |
99.1.4 List and ComboBox on Windows NT</h4> | |
On Windows NT only, you should avoid creating items in a List or ComboBox with strings longer than 1000 characters. | |
Doing so may result in a General Protection Fault. This has been fixed in more recent versions of Windows. | |
<h4> | |
99.1.5 BiDi Support</h4> | |
The StyledText widget now provides bidirectional language support for Hebrew and Arabic locales. | |
Currently, this support is available only on win32, and has several known problems. It should be | |
considered to be a preliminary implementation only. | |
<h4> | |
99.1.6 Cursor constructor arguments</h4> | |
In the constructor <code>Cursor(Device device, ImageData source, ImageData mask, int hotspotX, int hotspotY)</code>, | |
when both a source and mask argument are specified (i.e. mask is not null), the meaning of the two arguments is | |
reversed. That is, the "mask" argument should be the source image and the "source" argument should be the | |
mask image. This problem was discovered too late in the development cycle to be fixed for R1.0. The intent is to | |
fix this in a future release, potentially by introducing a new more general constructor. | |
<h4> | |
99.1.7 Use of the "&" character in TabFolder</h4> | |
The "&" character is not currently supported in TabFolder labels. Doing so on win32, will cause the | |
character which follows the "&" to be underlined as if it was a mnemonic, even though mnemonics are | |
not available for TabFolders. On other platforms, the "&" character will be displayed correctly, but | |
for portability reasons, it should be avoided. | |
<h4> | |
99.1.8 ToolBar on Windows</h4> | |
On Windows, you must create all tool bars with the FLAT style bit set. If you do not do this, | |
the "hot" (rollover) images of <em>all</em> toolbars may display incorrectly. | |
This will be fixed in a future release. | |
<h4> | |
99.1.9 Non ASCII strings on Linux</h4> | |
On Linux RedHat 6.2 only, you will not be able to display text that contains non | |
ASCII characters. This limitation is not present on Linux RedHat 7.1 or higher. | |
