In this project it shows there's no way to view a disabled state of a Developer Express TcxButton:

This is the effect of running this project (both buttons are disabled):

Hi Serge,

I already sent you a private mail, but that got no response. I do not get any notification by email if there is a response to my item. So, this response of you has not been noticed by me, simply because I did not get an email notification.

Can you please look into this, it makes this forum quite useless for me.

I re-checked my settings and as far as I can see, I should be receiving notifications by email.

Regards ;-}

It still fails to show disabled statel!!

This is the start of my acLFPainter.pas:

Code:

//{$DEFINE VER16_1_4} // cxGrid version 16.1.4 and newer
//{$DEFINE VER14_1_2}
//{$DEFINE VER13_2_2}
//{$DEFINE VER12_2_3}
{$DEFINE VER12_1_6}
//{$DEFINE VER26}
{$DEFINE VER23}

Hello!

Your version of the DevEx is 12.1.6?

I think it is 11.2.9 The setting with Ver12_1_6 is the only one that works.

Again: I do not receive notifications by e-mail if you respond to an issue. PLEASE look into this.

Thank you. They do!!

cxButton is alphablended if disabled, but text is not changed, because old DevEx packages doesn't allow to change a color of text in disabled button.

Thanks, I think it never worked.

Again, I did not receive notification of your answer. It's not in my spam box either. It's just not sent!

I'm not sure I agree with you. The TcxButton has an array of colors (property Colors) of which DisabledText is one. So, there is a way, apparently, to display disabled text with a different color.

For a skinning of the DevExpress controls the LookAndFeel painters used, this is a special technology implemented by DevExpress for skinning of their controls.

For drawing of buttons the DrawButton procedure used:

Code:

procedure DrawButton(ACanvas: TcxCanvas; R: TRect; const ACaption: string; AState: TcxButtonState;
ADrawBorder: Boolean = True; AColor: TColor = clDefault; ATextColor: TColor = clDefault;
AWordWrap: Boolean = False; AIsToolButton: Boolean = False

You can find it in the acLFPainter.pas

Text is drawn there, but DevEx engine draws text later and we can't change a color there.

And we haven't access to the button's colors palette or local TcxButtonPainter, because cxLookAndFeelPainter used there we can override some procedures only.
