0006781: TJvComboBox does not have TextHint property published

Sat, 07 Mar 2026 13:24:59 +0100

TJvComboBox and TJvDBComboBox do not have TextHint property while TComboBox and TDBComboBox (runtime) have it. This property is very useful for modern UI. I see it with Delphi 12.2 but surely it is common in all Delphi versiones..

0006776: JvHidControllerClass raises exception (RsEDeviceCannotBeIdentified) during creation.

Tue, 17 Sep 2024 14:34:10 +0200

As reported as https://github.com/project-jedi/jvcl/pull/56 on device Surface Pro the problem still occurs.
I have update windows to Win11 but the problem isn't fixed.
I create a workaround, but I don't like using custom JVCL library file.

if not HidD_GetAttributes(HidFileHandle, FAttributes) then
raise EControllerError.CreateRes(@RsEDeviceCannotBeIdentified);

to

HidD_GetAttributes(HidFileHandle, FAttributes);

0006772: JvBalloonHint not visible when using Remote Desktop

0006771: JvCheckTreeView: various problems

Tue, 11 Jun 2024 10:31:40 +0200

Working with Delphi 12.0

Adding a JvCheckTreeView component to a form and adding an item to it, at design time, causes the program to crash at runtime.

Working with Delphi 11.3

I was trying to disable the ability to check or uncheck checkboxes in a JvCheckTreeView.
The ReadOnly property only disables item caption editing.
It seems to me that the OnToggled, OnToggling, OnCheckStateChanged and OnCheckStateChanging events never fire.
I also found that the onChanging event fires when a new item is selected, but setting AllowChange := False doesn't prevent the change.

Just for the record I found a solution to my problem using the OnNodeCheckedChange event, by toggling the event before and after assigning the old state of the checkbox; not very easy...

0006706: JvDBGrid.EditControls is not working properly.

Fri, 31 May 2024 23:03:23 +0200

I checked JvDBLookupComboEdit and JvDBDatePickerEdit.
The drop-down list does not expand after editing or clicking the mouse.
In component version 3.5 it was correct.

0006718: Issue reported with JvTFAlarm not triggered

Tue, 02 Jan 2024 22:46:21 +0100

JvTFAlarm was reported to not trigger an Alarm event, based on an appointment being set. Discovered that in order for alarm to trigger, a Resources name/string (TStrings) must be entered (in the Resources field of the control) matching the resource name used in the appointment database/table where an appointment is saved. Alarm then triggers on-time as well as the snooze feature working. Tested with version 3.50 of JVCL build. Using Delphi 10 Professional (Seattle) version.

0006044: Add a power operator

Tue, 02 Jan 2024 21:24:16 +0100

I'd like to see a power operator added to the expression evaluator. My personal choice would be to use ^. There would need to be an extra precedence level introduced. So the operator precedence list would look like this:

// (highest) not bnot(bitwise) +(unary) -(unary) (level 4)
// ^ (level 3)
// * / div mod and band(bitwise) shl shr (level 2)
// +(binary) -(binary) or xor bor(bitwise) bxor(bitwise) (level 1)
// (lowest) < <= > >= cmp = <> (level 0)

0006346: TEvaluator doesn't work anymore with floating point values with Italian decimal separator

Tue, 02 Jan 2024 21:15:11 +0100

With previous version, till last JCL commit (30th septembar) ,all works fine.

I'm working on an italian machine so my default DecimalSeparator is "," and not ".".

I'm not able to evaluate expression because I don't know how to pass decimal separator in strings:

if I use Evaluator.Evaluate('123,45*9') I get: "Parse error: Unknown symbol: 123"
if I use Evaluator.Evaluate('123.45*9') I get: "123.45 in not a valid floating point value"

The workaround to make it work is this:

...
OldSep:=FormatSettings.DecimalSeparator;
try
FormatSettings.DecimalSeparator:='.';
VCalc:=Evaluator.Evaluate('123.45*9');
finally
FormatSettings.DecimalSeparator:=OldSep;
end;
