Failed to restore the position of TScrollPagerTool after SetUpScrollPager() called?
Find the example project.

Hi elmec,

I'm not sure about which is your exact problem. Using our current sources, when I resize the form, the ColorBand in the ScrollPager tool stays in the correct position. Is this your problem? Otherwise, can you provide more detailed information about the issue?

Thanks in advance.

It seems like the same problem with TRectangleTool..

Before get the position of TScrollPagerTool, did I need to call Draw() function?

Thanks in advance.

I'm not able to reproduce the problem you showed in the video either using the .exe you attached nor compiling your project here. Both exhibit the same behavior, clicking on the chart the ScrollPager tool is not resized nor relocated.

So what should I go to DO?
BTW, I am using the 201309XE4..the newest version released last month.

Best Regards.

Please follow the following steps to reproduce the issue.
1). Change the StartValue and EndValue of TScrollPagerTool to the value instead of default,
2). Resize the TChart.
3). Click on the TChart.

I think you missed the step 1...

We cannt wait for the next release because we are going to release our software.

Hello elmec,

First, I must apologize for our delay.
We have tried on several machine setups to reproduce the problem without success; is the problem reproducible on different machine setups or is there some particular (ie. Windows/Graphics-card) combination where the problem shows up. If you can help us with further information to recreate the
problem we'll investigate right away.

Thanks in advance.

Thanks..and Happy New Year!

I have 3 PCs, all of which can reproduce the problem.
They are Panasonic CF-B11(64Bit), DELL Dimension E521(32Bit) and DELL Vostro 260(32Bit).
so I don't think there are any particular combination..

I will attach the Exe file, would you please try it again using it,
NOT using the recompiled one.

Anyway, I will attach the video again to make the steps clearly..

The file is too big, so I upload them here.

Another bug? that is similar to the previous one.

It seems working well when I tried to change the position fo ColorBandTool of TScrollPagerTool,
but when I move the mouse into the TChart, the position was changed back to old position.

I also uploaded the exe file, video, and source here.

I think the problem is because of some event like _ColorBandChange_ not triggled,
so I checked the source of the TeeScrollPagerTool.pas..
and found that there is a procedure called ColorBandChanged..
then I added the code like the way of ColorBandChanged after
I assigned values to StartValue and EndValue...like the following..
And it seems that the problem is fixed..

Code: Select all

	double start = ScrollPager->ColorBandTool->StartValue;
	double end   = ScrollPager->ColorBandTool->EndValue;

	ScrollPager->SetUpScrollPager();
	ScrollPager->ColorBandTool->Color      = claGray;
	ScrollPager->ColorBandTool->StartValue = start ;
	ScrollPager->ColorBandTool->EndValue   = end;

	Chart->BottomAxis->SetMinMax(start, end);

Hello elmec,

We could reproduce the problem here but haven't found a satisfactory solution yet, it is not an easy one. In the meantime, could you please add the issue to http://bugs.teechart.net/?

Thanks in advance.
