    <p>I have a struct: </p> <pre><code>typedef struct { Qt::Key qKey; QString strFormType; } KeyPair; </code></pre> <p>Now I initialize KeyPair instantiations so I could use it for my Automated Test App. </p> <pre><code>KeyPair gDial[] = { { Qt::Key_1 , "MyForm" }, { Qt::Key_1 , "SubForm" }, { Qt::Key_Escape, "DesktopForm" } }; KeyPair gIP[] = { { Qt::Key_1 , "MyForm" }, { Qt::Key_2 , "Dialog" }, { Qt::Key_2 , "Dialog" }, { Qt::Key_Escape, "DesktopForm" } }; .... and like 100 more instantiations.... </code></pre> <p>Currently, I call a function which uses these KeyPairs.</p> <pre><code>qDebug() &lt;&lt; "Testing Test Menu"; pressKeyPairs( gDial); qDebug() &lt;&lt; "Testing Browse Menu"; pressKeyPairs( gIP); .... and more calls like this for the rest... </code></pre> <p>I would like to put all these KeyPair instantiations in a MAP so I wouldn't have to call pressKeyPairs() and qDebug() a hundred times... I'm a newbie in using MAPS... so I tried: </p> <pre><code>map&lt;string,KeyPair&gt; mMasterList; map&lt;string,KeyPair&gt;::iterator it; mMasterList.insert( pair&lt;string, KeyPair&gt;("Testing Test Menu", *gDial) ); //which I know is wrong, but how? mMasterList.insert( pair&lt;string, KeyPair&gt;("Testing IP Menu", *gIP) ); mMasterList.insert( pair&lt;string, KeyPair&gt;("IP Menu2", *gIP2) ); .... for ( it=mMasterList.begin() ; it != mMasterList.end(); it++ ) { qDebug() &lt;&lt; (*it).first &lt;&lt; endl; pressKeyPairs((*it).second); // I don't know how to access .second ... this causes a compiler error } </code></pre> <p>EDIT: pressKeyPairs is declared as: </p> <pre><code>template &lt;size_t nNumOfElements&gt; void pressKeyPairs(KeyPair (&amp;keys)[nNumOfElements]); </code></pre> <p>This code block isn't working... :( Can somebody tell me how to properly put these KeyPairs in a Map? </p>

    1. COThat is the definition of `pressKeyPairs` and what is your compile error?

    2. COWhat's the compiler error you're getting? Also, my guess would be that pressKeyPairs() gets a const KeyPair& but you're using an iterator instead of a const_iterator (as you should probably do anyway, because it's "more correct")

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.
