GuiScrollCtrl::scrollToBottom won't scroll to the bottom unless on console

[Axolotl]

BLTGuiScroll.scrollToBottom(); only works when entered through console.

Victimized code:

Code: [Select]

function BLT_PushLine(%line)
{
txtBLTGui.addText(" <color:" @ $Pref::BLT::FontColor @ "><font:" @ $Pref::BLT::FontName @ ":" @ $Pref::BLT::FontSize @ ">" @ %line @ "<br>",1);
BLTGuiScroll.scrollToBottom();
}


function BLT_PushError(%line,%error)
{
%errorpre = " <color:" @ $Pref::BLT::FontColorError @ "><font:" @ $Pref::BLT::FontNameError @ ":" @ $Pref::BLT::FontSize @ ">ERROR: ";

//- ERROR SCHEMES
//-- 0: No information available or custom error
//-- 1: Command not found
//-- 2: Server timed out
//-- 3: Server cancelled timeout without a timeout process running
switch(%error)
{
case 0:
txtBLTGui.addText(%errorpre @  %line @ "<br>",1);
case 1:
txtBLTGui.addText(%errorpre @  "Command not found: " @ %line @ "<br>",1);
case 2:
txtBLTGui.addText(%errorpre @  "Server timed out for command: " @ %line @ "<br>",1);
case 3:
txtBLTGui.addText(%errorpre @  "Server tried to stop timeout, but the timeout event wasn't present<br>",1);
default:
txtBLTGui.addText(%errorpre @  "Unknown Error (" @ %error @ "): " @ %line @ "<br>",1);
}
BLTGuiScroll.scrollToBottom();
}

Please tell me why the GUI won't scroll to the bottom unless the command is entered through console.

I'll try making it a GuiMLScrollCtrl
That doesn't exist, might've been Greek2Me's typo.

[Headcrab Zombie]

But the addText in that function is working just fine?

Yep

[TripNick]

Just for testing purposes, try changing that line to BLTGuiScroll.schedule(1000, scrollToBottom);

It could be an issue with adding the text then scrolling so quickly after. If this works you could probably reduce the schedule to 0 or 1, the 1000 is just so it's obviously delayed and thus you know the line worked.

100 is a working delay

Also, thank you.

Yeah you need a delay, but even then, it looks stuffty.

Instead use gui.resize();
i think if you resize it so it is on the bottom of the scroll control, it would be exactly like the scrolltobottom function except you can control it better.

[M]

If you use .resize(x,y,w,h) on the child and then .schedule(0,"scrolltobottom") on the scroll it should work fine
It just needs a tick to update the child height. There'll still be a tiny flash of the new height before it scrolls.

Also, look into GuiMessageVectorCtrls. You'd have to make a custom profile, set their font face and size on it, and set their font colors in .fontColor[0-9] to style it (and you can't do substyles), but when you push a line on a message vector it automatically scrolls the parent scrollctrl. Stupid hacked in functionality there, but it does work (RTB chats use these, last I checked)

if you use .resize() with the right math, the scrolltobottom isnt needed at all
