|
|
|
|
|
|
The TQInputDialog class provides a simple convenience dialog to get a single value from the user.
|
|
|
|
|
|
<p> The input value can be a string, a number or an item from a list. A
|
|
label must be set to tell the user what they should enter.
|
|
<p> Four static convenience functions are provided:
|
|
<a href="#getText">getText</a>(), <a href="#getInteger">getInteger</a>(), <a href="#getDouble">getDouble</a>() and <a href="#getItem">getItem</a>(). All the
|
|
functions can be used in a similar way, for example:
|
|
<pre>
|
|
bool ok;
|
|
<a href="ntqstring.html">TQString</a> text = TQInputDialog::<a href="#getText">getText</a>(
|
|
"MyApp 3000", "Enter your name:", TQLineEdit::Normal,
|
|
<a href="ntqstring.html#TQString-null">TQString::null</a>, &ok, this );
|
|
if ( ok && !text.<a href="ntqstring.html#isEmpty">isEmpty</a>() ) {
|
|
// user entered something and pressed OK
|
|
} else {
|
|
// user entered nothing or pressed Cancel
|
|
}
|
|
</pre>

|
Static convenience function to get a floating point number from
|
|
the user. <em>caption</em> is the text which is displayed in the title
|
|
bar of the dialog. <em>label</em> is the text which is shown to the user
|
|
(it should say what should be entered). <em>value</em> is the default
|
|
floating point number that the line edit will be set to. <em>minValue</em> and <em>maxValue</em> are the minimum and maximum values the
|
|
user may choose, and <em>decimals</em> is the maximum number of decimal
|
|
places the number may have.
|
|
<p> If <em>ok</em> is not-null <em>*</em><em>ok</em> will be set to TRUE if the user
|
|
pressed OK and to FALSE if the user pressed Cancel. The dialog's
|
|
parent is <em>parent</em>; the dialog is called <em>name</em>. The dialog will
|
|
be modal.
|
|
<p> This function returns the floating point number which has been
|
|
entered by the user.
|
|
<p> Use this static function like this:
|
|
<p> <pre>
|
|
bool ok;
|
|
double res = TQInputDialog::<a href="#getDouble">getDouble</a>(
|
|
"MyApp 3000", "Enter a decimal number:", 33.7, 0,
|
|
1000, 2, &ok, this );
|
|
if ( ok ) {
|
|
// user entered something and pressed OK
|
|
} else {
|
|
// user pressed Cancel
|
|
}
|

</pre>

Static convenience function to get an integer input from the

user. <em>caption</em> is the text which is displayed in the title bar

|
of the dialog. <em>label</em> is the text which is shown to the user

integer which the spinbox will be set to. <em>minValue</em> and <em>maxValue</em> are the minimum and maximum values the user may choose,
|
|
and <em>step</em> is the amount by which the values change as the user
|
|
presses the arrow buttons to increment or decrement the value.
|

<p> If <em>ok</em> is not-null *<em>ok</em> will be set to TRUE if the user

Static convenience function to let the user select an item from a
|
|
string list. <em>caption</em> is the text which is displayed in the title
|
|
bar of the dialog. <em>label</em> is the text which is shown to the user (it
|
|
should say what should be entered). <em>list</em> is the
|
|
string list which is inserted into the combobox, and <em>current</em> is the number
|
|
of the item which should be the current item. If <em>editable</em> is TRUE
|
|
the user can enter their own text; if <em>editable</em> is FALSE the user
|
|
may only select one of the existing items.
|
|
<p> If <em>ok</em> is not-null <em>*</em><em>ok</em> will be set to TRUE if the user
|

pressed OK and to FALSE if the user pressed Cancel. The dialog's

parent is <em>parent</em>; the dialog is called <em>name</em>. The dialog will

|
be modal.
|
|
<p> This function returns the text of the current item, or if <em>editable</em> is TRUE, the current text of the combobox.
