    <p>Here I'm creating a button with a function called when button is pressed</p> <pre><code>local politeButton = widget.newButton { left = 35, top = 335, width = 70, height = 70, defaultFile = "images/politeRu.png", overFile = "images/politeWhiteRu.png", onPress = politeGenerator, } </code></pre> <p>and here's the function (actually it's coded up above the button)</p> <pre><code>math.randomseed(os.time()) local function politeGenerator() local firstRandomPart = math.random(1,3) local secondRandomPart = math.random(1,3) local thirdRandomPart = math.random(1,3) local firstComplPart = {"I love", "I need", "I beg"} local secondComplPart = {" you like mad ", " the color of your eyes ", " your lips "} local thirdComplPart = {"and I wish you are going to be mine!", "and I am shivering!", "and this is all I want!"} local politeCompliment = firstComplPart[firstRandomPart]..secondComplPart[secondRandomPart]..thirdComplPart[thirdRandomPart] local complimentItself = display.newText(politeCompliment, 30, 150, 200, 200, "Lobster", 18) end </code></pre> <p>Ok, now I see some randomly generated text in the simulator. But when I press the button once again the old text doesn't disappear and new text is appear on the old text and so on. But I need text to be overwritten every time press the button. I tried <code>event.phase == "began"</code>, I tried <code>complimentItself:removeSelf()</code> but all in vain. Can anyone help, please? I just don't understand why the variable doesn't get overwritten when I press the button.</p>

    1. COIs `complimentItself` the new widget that contains the text you just created? If so you lose your reference to it when the function exits and you can't remove it later. So each time through the function you create a new widget and never remove the old ones. You need to keep the old reference around and remove it from the display I would imagine (though I know nothing about corona).

    2. COEtan, thanks for your participation, your suggestion makes sense to me, but I still don't get "how to" or I don't understand where's exactly my mistake.

    3. COYou either use a global (or outer local) to store the old reference and remove it when politeGenerator is run again or you find out how to hook up some other mechanism (event, signal, etc.) to let the text widget know that it needs to remove itself. I can't be more specific since I don't know enough about corona. The global/outer local route is certainly simplest.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
