| 36 | <p> The <tt>chart</tt> application shows how straight-forward it is to create
|
|---|
| 37 | applications and their dialogs with Qt. Creating menus and toolbars is
|
|---|
| 38 | easy and Qt's <a href="signalsandslots.html">signals and slots</a>
|
|---|
| 39 | mechanism considerably simplifies GUI event handling.
|
|---|
| 40 | <p> Manually creating layouts can take some time to master, but there is
|
|---|
| 41 | an easy alternative: <a href="designer-manual.html">Qt Designer</a>.
|
|---|
| 42 | <a href="designer-manual.html">Qt Designer</a> includes simple but
|
|---|
| 43 | powerful layout tools and a code editor. It can automatically generate
|
|---|
| 44 | <tt>main.cpp</tt> and the <tt>.pro</tt> project file.
|
|---|
| 45 | <p> The <tt>chart</tt> application is ripe for further development and
|
|---|
| 46 | experimentation. You might consider implementing some of the following
|
|---|
| 47 | ideas:
|
|---|
| 48 | <ul>
|
|---|
| 49 | <li> Use a <a href="qvalidator.html">QValidator</a> subclass to ensure that only valid doubles are
|
|---|
| 50 | entered as values.
|
|---|
| 51 | <li> Adding more chart types, e.g. line graph, area graph and hi-lo
|
|---|
| 52 | graph.
|
|---|
| 53 | <li> Allowing the user to set top, bottom left and right margins.
|
|---|
| 54 | <li> Allowing the user to specify a title which they can drag into
|
|---|
| 55 | position like the labels.
|
|---|
| 56 | <li> Providing an axis drawing and labelling option.
|
|---|
| 57 | <li> Providing an option to provide a key (or legend) instead of labels.
|
|---|
| 58 | <li> Adding a 3D look option to all chart types.
|
|---|
| 59 | </ul>
