this is a reporting of bugs in the TextField class of the java developers
kit 1.0.
these bugs appear on the sparc-sun-solaris2.4 system.
source code attached.
use the following commands:
javac tsi.java
appletviewer tsi.html
in the resulting display, please note the following problems:
1) note that the insertion point only blinks while the mouse is moving.
in particular, if the cursor is hidden when the mouse stops, then it
remains hidden until you move the mouse some. but don't move it too long!
2) while mouse is within the frame of the applet, note that cpu
utilization goes to 100% if there are text fields present.
3) try double clicking on the word foo. note that double clicking in a
text field has to be very fast to actually select a word.
4) double click on the word foo and then click once after the word cough.
note that foo is not deselected.
5) click after the word cough and move the cursor up to the word foo,
then wiggle it just enough so that you can see the insertion point after
cough while keeping the cursor centered over foo. without moving the
mouse, double click on foo. note that foo is hilited but that there is an
insertion point artifact left on cough.
6) now press the tab key. note that it cycles through the text fields,
not moving the selection as it moves from field to field. you can get in
the curious state of having a blinking insertion point and a hilited
selection at the same time.
7) note the text fields are more than one line tall. they should not
allow themselves to be taller than one line.
some text field requests:
1) macintosh rules: tabbing to a field selects text if non-empty.
