Re: [platform-swt-dev] Borders like org.eclipse.swt.widgets.Text and org

[Damien Dudouit <ddudouit@xxxxxxx>]

Hello,

Thanks a lot Arun and Markus for your answers.

I expected it would not be possible but then I was put in doubt by the DateTime widget which extends Composite and yet has is.

By the way, the effect is not just on focus in but also on mouse over. On windows 7, the border is slightly rounded and bi-color (the top is darker) and there is a color transition when the color change (by default between gray and blue), while on the same machine the border we get with new Composite(parent, SWT.BORDER) is rectangle with no rounding and with a single color (I have attached a screenshot).

It would be great to have a style INPUT_BORDER to be able to code custom input widgets that yet behave natively in that respect (border highlight on focus in and mouse over).

Thanks,

Damien

Hi Damien

> How can I get such a border on a custom control ?

Sorry, you can't. There's currently no API to get this in SWT.

This "focus" border around the active Text/Combo/Date is something the OS
provides for these special widgets. (Windows turns the border blue; Mac
add's a blue "focus ring" around.)

You can't see the implementation in the DateTime class because it's really
not there. :-) DateTime is only a Composite because it used to be emulated
on platforms that didn't offer such a widget.

You can file an enhancement request for SWT, but I'm not sure if this can
be implemented for non-native widgets. See e.g. StyledText and CCombo,
which also don't show a focus ring.

Hi Damien,

I'm not sure I understand your question completely.
What exactly do you mean by a border that changes on focus in? Did you
mean
that this change is happening now on Windows 7 & Mac OS X but not on
Linux?

I would suggest posting this query with more details (including screen
shots if possible) on the SWT community forum (
https://www.eclipse.org/forums/index.php/f/100/) which is more appropriate
for queries of this kind.

Thanks,
Arun

Hello,

I would like a control similar to org.eclipse.swt.widgets.DateTime, that
appears as a Text field but has several sub areas.
The problème for me is the border. On Windows 7 and MacOS X for instance,
widgets such as Text and DateTime have a border that change when the focus
is gained.

How can I get such a border on a custom control ?

The only way I know of to get a native border is :

public class MyWidget extends Composite {

  public MyWidget(Composite parent, int style) {
  super (parent, SWT.BODER);

but that border does nothing on focus in.


I have tried looking at the code of the DateTime widget but I don't manage
to see where the border is dealt with :

public class DateTime extends Composite {

  public DateTime (Composite parent, int style) {
  super (parent, checkStyle (style));


Thanks a lot in advance,

Regards,
