@BeeJay search the forum for ExcludeClipRect and you will find the code snippets I have posted before. My changes were required for the MDI tab groups, so probably not related to this core issue anyway.

pity this idea did not work for the shadows problem

@scottp: no not yet, I haven't dived that deep into windows painting details (yet) - I'll check this. Would you mind to provide information where you also have added ExcludeClipRect code in the sources, as we are facing flickering issues, too. I'd really appreciate this (and maybe others, too!). Clap

EDIT: Unfortunately adding this line does not change the effect. Cry

I have inserted this code here:

void CXTPFrameShadow::OnPaint()
{
    if (NULL == m_pPCD)
    {
        ComputeData();
    }

    CPaintDC dc(this);
    dc.ExcludeClipRect(m_pPCD->clientRect);


Is this right? Maybe we need your other ExcludeClipRect additions, too?]]> Tue, 20 Oct 2015 05:51:59 +0000 http://forum.codejock.com/forum_posts.asp?TID=22747&PID=74047&title=more-cj-17-beta-3-shadow-woes#74047 <![CDATA[More CJ 17 beta 3 shadow woes : have you tried something like...]]> http://forum.codejock.com/forum_posts.asp?TID=22747&PID=74046&title=more-cj-17-beta-3-shadow-woes#74046 Author: scottp

have you tried something like this in CXTPFrameShadow::OnPaint?
dc.ExcludeClipRect(m_pPCD->clientRect);

We have needed to patch XTPTabClientWnd.cpp in several places to add ExcludeClipRect to help avoid flicker

would there be an option not to draw a full solid black rectangle for the Shadow but just to leave out the whole internal part?

see the attached animated gif (I hope the forum software does not break it up)

This can help, especially with terminal sessions. But I have to turn off shadows due to the other issue where none of my web browser controls created after a resize operation function properly. I already commented out code for setting the window pos (including doing nothing by just returning from the Drag method by adding "return;" at the top of the method) so I'm guessing that even with the shadow not displayed but enabled for resize, I'll encounter the browser control problem, including the lockups I can get when navigating when a resize is in progress where all that seems to be executing when I pump messages is the shadow hooking code.

Basically, hard to tell until I get hold of the new code.

Hi Alexander,

> As long as re-designing shadows is not a option, the problem has been solved by adding global Frame Manager flags

This seems like a reasonable compromise.

When will a new build be available to us for testing?

Regards,

Mark R.

As long as re-designing shadows is not a option, the problem has been solved by adding global Frame Manager flags:

enum XTPFrameShadowManagerFlags
{
// Frame shadows disabled. When this flags is set the existing shadow made
// invisible and not resizeable (xtpFrameShadowsInvisible | xtpFrameShadowsNotResizeable
// get enabled automatically) but no new shadows will be created for new windows.
xtpFrameShadowsDisabled = 1,

// Frame shadows are not visible but remain resizeable.
xtpFrameShadowsInvisible = 2,

// Frame shadows cannot be used for resizing the owner windows.
xtpFrameShadowsNotResizeable = 4,

// Frame shadows are automatically disabled for Terminal Services sessions, 
// e.g. Remote Desktop Connection. When it's set and a Terminal Services 
// session is detected all existing and new shadows will be made invisible 
// and not resizealbe (xtpFrameShadowsInvisible | xtpFrameShadowsNotResizeable).
// Once terminal session abandoning is detected those flags
// will get restored to their original values.
xtpFrameShadowsDisabledInTSS = 8,

// Frame shadows are automatically invisible for Terminal Services sessions, 
// e.g. Remote Desktop Connection, but remain resizealbe.
xtpFrameShadowsInvisibleInTSS = 0x10
};

Please let me know your thoughts on it.
Regards,
  Alexander

I had to disable the shadow for all sessions due to the other issues it is causing like keeping web browser controls from working. As for remote sessions, I agree these fancy graphics are problematic. However, I was running our app via Visual Studio and VS has a shadow, just implemented differently, and I didn't notice an issue with it.

I do like the new resizing ability the shadow achieves, but the pain isn't worth the gain! Couldn't the tracking the shadow window gives can be achieved with a window that draws ... nothing.

Drawing semi-transparent graphics will always cause performance issues when run remotely, this is the reason why most of remote desktop software disable DWM and other niceties by default. Creating 4 semi trasparent underlying windows instead of one layered will probably make it a little bit faster for the price of reduced functionality and customizability of the shadow, but it might cause other unexpected issues in its turn. One possible solution that I can suggest, and please tell me what you think about it, is to optionally disable all frame shadows when connected remotely.]]> Tue, 13 Oct 2015 22:27:00 +0000 http://forum.codejock.com/forum_posts.asp?TID=22747&PID=74021&title=more-cj-17-beta-3-shadow-woes#74021
