Summary0000200: update to JvComCtrls: TJVPageControl
Description0) {$IFDEF LINUX} This unit is only supported on Windows! {$ENDIF}
I think there should not be such a line!
We should check for {$IfNDef WIN32} instead
Or better we should rely on Jedi.Inc - see extra info in attached file.

Also i integrated one of my components - i contributed it as Later i'll do it with RxCheckBox.

Also - icon for TJvPageControl updated.
I wonder, Do delphi support palletised 16-coloured bitmaps?
ImageEdit - do not :(
TagsNo tags attached.

i fix (re-query hint, when mouse is moving over items of the control)

In CMShowHitn method:
    if Choice=cT then HintStr:=GetShortHint(Tab.Hint);
Change to:
    if Choice=cT then begin

This will be revisited when updating to JVCL 3.0

I tested this but it seems CM_HINTSHOW is never called (in D6)? Also, D6 and D7 displays the tabs hint when the mouse is over the tab client area and the page control hint when the mouse is over the tab. Isn't this what your code does as well (or would do if it worked)?

as: demo is for Delphi7, You may unpack with

by default it works exactly in standard PageControl manner.
But change HintSource property - and try again.

Just hold the mouse (i needed to click on PageControl before :( ) over tab #3 (not sheet) for both PageControls and compare hints.

Please use zip when you upload files. I am not going to install yet another compression program just to unpack this demo and I seriously doubt that anyone else will either.

I'm seriously thinking about using 7zip:

Solid archiving will save A LOT of spaces.
Some times ago You told RAR will never be used since it is commercial software.
No i'd like You to consider 7-zip cause it is GPLed freeware and packs the same good as RAR (smth better, smth worse)
And to the end it has it's own 2-paneled file manager :-)

I'll repack to ZIP, but indeed 7-zip is MUCH stronger than any other zero-priced archiver, and there is nothing bad to give it a try.

also i'll post a sreenshot, so take a look at hints displayed for:
TForm, TabSheet1 for both original and modified TPageControl, tab associated to TabSheet1 for both..., tab associated to TabSheet3....

And sure you can take latest sources from demo, or You can take original zip and apply the patch above :-)

The bugs are still here.
Year after i told about them in jedi.vcl newsgroup and gave fixes, and heard a replies...

I wonder why this donation was accepted, if later it was broken and was never fixed ?

What bugs? The only difference I can see is the CursorRect assignment for Tab hints. Is there any more?


2004-11-12 12:52

developer   ~0005619

There were more. In the versions i posted to jedi.vcl.
I don't have them on the fingertips, so i hope someone else do.

Did You run testcase?
There is told all the troubles.

>Did You run testcase?
I made my own with the TJvPageControl and the only issue is that when the mouse is over the tab page (not the tab itself), no CM_HINTSHOW is sent to the PageControl, so we can't modify the behavior in that case.

Other than that, i couldn't find anything that was misbehaving.

Let's discuss it in the newsgroup beter, ok ?

>no CM_HINTSHOW is sent to the PageControl, so we can't modify the behavior in that case.
And it should not IMHO, so i do not know, what you called an issue and how You need to change behavior.

>> Did You run testcase? There is told all the troubles
> I made my own
I just want to repeat, that TestCase is self-documented, as every good testcase is to be.
I can paste DFM text here of course, but it is simplier IMHO to run test and read what is written on its form :-)

An update is committed to CVS

Please try with the latest zip files and tell us if the problem is fixed. These files are available here:

If we don't hear from you in the next 14 days, we will consider this issue fixed.

i did not look the code yet, i just recompiled my testcase with daily update

Test 2 - seems to be fixed
Test 1 - Move mouse cursot over Tab 2 until hint for TabSheet 2 pops up.
Then move mouse to the right, until hint for the Main PageControl pops up.
After that move mouse back to Tab 2 - hint should change, but it does not.


2005-08-10 08:34

administrator   ~0007782

I'm marking this as resolved because test 1 is ok.
Further to this, I tried to reproduce test 2, but the hint only shows up when the tabsheet is active, not when merely hovering its tab. Please post a new issue if need be.
