DButton not working

[Megolas]

Hey,

I'm currently working on a GUI for a shop, and I have this DButton's who text align got glitchy (Should be centered), The text (Buy) got cut off to B..., it doesn't change its look when I hover over it and its DoClick function doesn't run... Is anyone familiar with this issue and can help?

This is what it looks like:

The button itself is inside a panel which is inside a pane.

Thanks

Show code of your button.

Tried to narrow it down as much as I could:

	self.rightPane = vgui.Create("DPanelList", self);
	self.rightPane:EnableVerticalScrollbar(true);
	self.rightPane:SetSpacing(6);
	self.rightPane:StretchToParent(self.categoryList:GetWide()+8, 4, 4, 4);
	local gradient = surface.GetTextureID("VGUI/gradient_down");
	local quadObj = {
		texture = gradient,
		color = Color(0, 0, 0, 200),
		x = 0,
		y = 0,
		w = ScrW()
	};
	function self.rightPane:Paint()
		quadObj.h = self:GetTall();
		draw.TexturedQuad(quadObj);
	end;
	local buttonPanel = vgui.Create("DPanel");
	buttonPanel:SetTall(30);
	buttonPanel.useButton = vgui.Create("DButton", buttonPanel);
	buttonPanel.useButton:SetTextColor(Color(255, 255, 255));
	buttonPanel.useButton:SetSize(self.rightPane:GetWide(), 30);

	buttonPanel.useButton:SetText("Buy");
	buttonPanel.useButton:SetZPos(1000);
	buttonPanel.useButton.DoClick = function()
		print("Sending buy command")
	end;

	self.rightPane:AddItem(buttonPanel);

I might have missed some things in the middle, connecting the parts, but I can't spot any currently

Here's a quick tip for less code:

local but = vgui.Create("DButton", buttonPanel)
but:SetTextColor(Color(255, 255, 255))
but:SetSize(self.rightPane:GetWide(), 30)

but:SetText("Buy")
but:SetZPos(1000)
but.DoClick = function()
	print("Sending buy command")
end

buttonPanel.useButton = but

And what's up with all the semicolons? Lua doesn't need those.

Sorry, I can't help you with the problem. Running that button code works just as fine, I you could try doing something like but:InvalidateLayout(true) after self.rightPane has it's width set up.

Thanks for the tips - it didn't work, but I found something else:
The functions are nested the following way:

PANEL:Layout()
|-->other functions
|-->Last thing ran before the function ends: function that draw button

Now, I found out hat if I create an error after the last line that run, everything works again. But nothing is supposed to run after that, so I see no reason that should happen - is there some function being run when a panel finishes its layout?

DButton consists of several vgui elements. The Button, a Label and sometimes an Image. Stretching it may only resize the Button, SizeToContents( ) stretches the Label to the length of text.
Call SizeToContents( ) after setting the text, and after stretch to parent
