Hello Like to Know What's Best Way to Make a repaint in Controls in Runtime
I Did So I wonder if this correct
Thank You for reading and Reply.
var
I: Integer;
begin
for I := 0 to ComponentCount -1 do
begin
if Components is TsSpeedButton then
if TsSpeedButton(Components).SkinData.SkinSection = 'BUTTON_HUGE' then
begin
TsSpeedButton(Components).SkinData.CustomFont := True;
TsSpeedButton(Components).Font.Color:= ClWhite;
end;
end;
sSkinManager1.RepaintForms;
end;
I noticed a couple of releases back that some buttons and other controls in my apps weren't refreshing when font and color properties were being updated. It had worked in the past but suddenly I had to code around it. I think it's actually a bug – setting the colour *should* have an immediate effect without any more code. Anyway you can easily code around it as you've done, or more efficiently just refresh the control you're altering with a call to invalidate, refresh or repaint (normally invalidate but it depends on the control).
TsSpeedButton(Components).Invalidate;

Hi Hamilton,
I've noticed in a few controls there still exist a few refresh problems…they're not always refreshed EVERY time. I'm linking a few speed buttons to various alphaimagelists then changing their image index…most times it works but sometimes the image won't refresh until you either move the mouse over the button, or move away from the form/page and come back to it. It doesn't happen every time and believe me I've tried combinations of Invalidate, Refresh and Repaint but they don't always work. I don't think thats a bug in the execution/coding of the controls I think it might just be a small bug in the *flow* of execution. I had an idea though…because obviously (my example of speed button not always refreshing) the image is 'there' cos it appears when mouse is moved over… do you think if the AC team (whilst the small 'bugs' are there) might implement a method/property of each control called something like
WhateverAlphaSkinsControl.EmergencyRedraw;
this would call the root code drawing of the item…that root code is there and it works cos …well my example again…image is shown when mouse is moved over control or page is changed then come back to…so drawing code is fine just not always the *updating* code. Maybe they're already doing that though cos thats what .Redraw is supposed to do? What do you think?
Wow cool day for me…
thinking about your advice on really finding out which of Invalidate, Refresh, Repaint would work for my speedbutton problem I tried them all and nothing. Then I did this
sspeedbuttonEditPreview.Invalidate;
sspeedbuttonEditPreview.refresh;
*together and in that order*
which kinda makes sense and i wonder why it didn't occur to me…invalidate says 'invalidate this'…then it makes sense to call the refresh to 'refresh what you just invalidated'. Anyway…it works for my problem here. Hope it helps someone else 🙂
EDIT UPDATE*** Tested for the last 30 mins in all areas of my main app that were experiencing button update problems. Looks as solid as a rock all update issues now gone *touch wood*
EDIT UPDATE 2*** It works all the time here…never had one fail yet after over 14 hours of solid programming/testing main app 🙂
Hello Friend Looks like I managed to do Work.
A Hug to All.

//TsSpeedButton(Components).Canvas.Refresh; does not work
//TsSpeedButton(Components).GraphRepaint; does not work
end;
end;
sSkinManager1.RepaintForms; //Only works well
end;

Hello All
TsSpeedButton will be repainted automatically in the nearest release.
Wesley, for a full repaint of Alpha controls may be used this code : TsSpeedButton(Components).SkinData.Invalidate

Thankyou Serge 🙂
Thank you my friend for your attention, but unfortunately I use TsSpeedButton (Components ). SkinData.Invalidate the event
sSkinManager1AfterChange and unfortunately it crashes when I switch skins. I use another event?
