Button not showing on frame

[Codger]

I'm a beginner when it comes to addon development...
I created a simple addon with a frame and a button but the button is not showing up on the frame.
I've looked at a few other examples but can't see what I'm doing wrong.
I have bug sack/bug grabber enabled and not seeing any errors.
Any help is much appreciated.

Here is my lua file.

-- Load the AceGUI and LibDBIcon libraries
local AceGUI = LibStub("AceGUI-3.0")
local LibDBIcon = LibStub("LibDBIcon-1.0")
 
-- Create a new frame
local frame = AceGUI:Create("Frame")
frame:SetTitle("MyAddon Frame")
frame:SetStatusText("Example Status Text")
frame:SetCallback("OnClose", function(widget) AceGUI:Release(widget) end)
frame:SetLayout("Flow")
frame:Hide()
 
-- Create a button
local button = AceGUI:Create("Button")
button:SetText("Click Me!")
button:SetWidth(200)
button:SetCallback("OnClick", function() print("Button Clicked!") end)
 
-- Add the button to the frame
frame:AddChild(button)
 
-- Create a minimap button
local showFrame = false
local icon = LibDBIcon:Register("MyAddon", {
    icon = "Interface\\Icons\\Ability_Marksmanship",
    OnClick = function(self, button)
        if button == "LeftButton" then
            frame:Show()
        elseif button == "RightButton" then
            frame:Hide()
        end
    end,
    OnTooltipShow = function(tooltip)
        tooltip:SetText("MyAddon")
        tooltip:AddLine("Left-click to open", 1, 1, 1)
        tooltip:AddLine("Right-click to close", 1, 1, 1)
    end,
})
 
-- Register the addon
local addonName, addonTable = ...
addonTable.frame = frame

frame:Hide()

Will hide the frame until you show it (presumably with the minimap button)

If you start off commenting out the Hide() until you've finished creating the frame and getting it working properly and then worry about the mechanics of showing/hiding it might prove useful.

Thanks for the help. Moving the :hide call fixed the button issue.
I also commented out the line:
--frame:SetCallback("OnClose", function(widget) AceGUI:Release(widget) end)
and now the button shows up with when the frame is opened and closed which makes me wonder when I should be concerned about release the widgets? Do most addons leave the frame open?

-- Load the AceGUI and LibDBIcon libraries
local AceGUI = LibStub("AceGUI-3.0")
local LibDBIcon = LibStub("LibDBIcon-1.0")
 
-- Create a new frame
local frame = AceGUI:Create("Frame")
frame:SetTitle("MyAddon Frame")
frame:SetStatusText("Example Status Text")
--frame:SetCallback("OnClose", function(widget) AceGUI:Release(widget) end)
frame:SetLayout("Flow")
 
-- Create a button
local button = AceGUI:Create("Button")
button:SetText("Click Me!")
button:SetWidth(200)
button:SetCallback("OnClick", function() print("Button Clicked!") end)
 
-- Add the button to the frame
frame:AddChild(button)
 
--frame:Hide()
 
-- Create a minimap button
local showFrame = false
local icon = LibDBIcon:Register("MyAddon", {
    icon = "Interface\\Icons\\Ability_Marksmanship",
    OnClick = function(self, button)
        if button == "LeftButton" then
            frame:Show()
        elseif button == "RightButton" then
            frame:Hide()
        end
    end,
    OnTooltipShow = function(tooltip)
        tooltip:SetText("MyAddon")
        tooltip:AddLine("Left-click to open", 1, 1, 1)
        tooltip:AddLine("Right-click to close", 1, 1, 1)
    end,
})
 
-- Register the addon
local addonName, addonTable = ...
addonTable.frame = frame

The game doesn't "destroy" widgets (frames, buttons etc). They remain until you /reload or logout.

I don't use Ace so I can only guess that at what releasing does, possibly some internal pool mechanaism for re-use. That said, just hiding/showing the frame to start with until you get more understanding of how Ace does things won't hurt.

Putting code blocks around code will make it more readable (the # or blue lua buttons above the edit box)

[Codger]

The code looks so much better.
I really appreciate all the help you provide!!
