Dialog box with an edit control
From Apache OpenOffice Wiki
We want now to construct the dialog box below.
We have to have a look at the corresponding IDL files. We begin with com.sun.star.awt.XTextComponent Interface.
//Listing 21 XTextComponent Interface : IDL File
// IDL
module com { module sun { module star { module awt {
interface XTextComponent: com::sun::star::uno::XInterface
{
[oneway] void addTextListener( [in] com::sun::star::awt::XTextListener l );
[oneway] void removeTextListener( [in] com::sun::star::awt::XTextListener l );
[oneway] void setText( [in] string aText );
[oneway] void insertText( [in] com::sun::star::awt::Selection Sel,
[in] string Text );
string getText();
string getSelectedText();
[oneway] void setSelection( [in] com::sun::star::awt::Selection aSelection );
com::sun::star::awt::Selection getSelection();
boolean isEditable();
[oneway] void setEditable( [in] boolean bEditable );
[oneway] void setMaxTextLen( [in] short nLen );
short getMaxTextLen();
};
}; }; }; };

As shown in Figure above this example has a defect : the text is always added on the top instead on the bottom ! At the moment, I don't know how to resolve this problem : If I use the setText method I always obtain only one line, if I use insertText method I have to provide a selection. I take this selection with the getSelection but there is nothing selected and then this method return the beginning of the text.
Talk: please see here So let's have a look at the com.sun.star.awt.Selection IDL file module com { module sun { module star { module awt {
struct Selection: com.sun.star.awt.Selection.
{
Min specifies the lower limit of the range.
Max specifies the upper limit of the range.
};
}; }; }; };

We show now the com.sun.star.awt.UnoControlEditModel IDL file :
//Listing 22 UnoControlEditModel Service : IDL File
// IDL
module com { module sun { module star { module awt {
service UnoControlEditModel
{
service com::sun::star::awt::UnoControlModel;
[property] short Align;
[property] long BackgroundColor;
[property] short Border;
[optional, property] short EchoChar;
[property] boolean Enabled;
[property] com::sun::star::awt::FontDescriptor FontDescriptor;
[property] short FontEmphasisMark;
[property] short FontRelief;
[property] boolean HScroll;
[property] boolean HardLineBreaks;
[property] string HelpText;
[property] string HelpURL;
[property] short MaxTextLen;
[property] boolean MultiLine;
[property] boolean Printable;
[property] boolean ReadOnly;
[property] boolean Tabstop;
[property] string Text;
[property] long TextColor;
[property] long TextLineColor;
[property] boolean VScroll;
};
}; }; }; };
We use any of these properties in the example above. To construct it, I modify first the event listener of the previous example like the listing above :
//Listing 23 We first remplace XFixedText with XTextComponent interface
// C++
....
// Don't forget to add : #include <com/sun/star/awt/XTextComponent.hpp>
// Don't forget to add "com.sun.star.awt.XTextComponent \" in the makefile
// Reference< XFixedText > xLabel(label,UNO_QUERY); //OLD
Reference< XTextComponent > xLabel(label,UNO_QUERY);
xLabel->insertText (xLabel->getSelection(),
OUString::createFromAscii("Text1 ") + OUStr.valueOf((sal_Int32)_nCounts)+
OUString::createFromAscii("\n"));
....
and then I replace the “com.sun.star.awt.UnoControlFixedTextModel” control with "com.sun.star.awt.UnoControlEditModel". This is done with code :
//Listing 24 The UnoControlEditModel : an Example
// C++
Reference< XInterface > xlabelModel = xMultiServiceFactory->createInstance(
OUString::createFromAscii("com.sun.star.awt.UnoControlEditModel"));
Reference< XPropertySet > xPSetLabel(xlabelModel,UNO_QUERY);
value=20; val <<= value;
xPSetLabel->setPropertyValue(OUString::createFromAscii("PositionX"),val);
value=10; val <<= value;
xPSetLabel->setPropertyValue(OUString::createFromAscii("PositionY"),val);
value=110; val <<= value;
xPSetLabel->setPropertyValue(OUString::createFromAscii("Width"),val);
value=50; val <<= value;
xPSetLabel->setPropertyValue(OUString::createFromAscii("Height"),val);
xPSetLabel->setPropertyValue(OUString::createFromAscii("HScroll"),makeAny((sal_Bool)true));
xPSetLabel->setPropertyValue(OUString::createFromAscii("VScroll"),makeAny((sal_Bool)true));
xPSetLabel->setPropertyValue(OUString::createFromAscii("MultiLine"),
makeAny((sal_Bool)true));
xPSetLabel->setPropertyValue(OUString::createFromAscii("HardLineBreaks"),
makeAny((sal_Bool)true));
val <<=OUString::createFromAscii("Label1");
xPSetLabel->setPropertyValue(OUString::createFromAscii("Name"),val);
xPSetLabel->setPropertyValue(OUString::createFromAscii("TabIndex"),makeAny((short)1));
We will construct a helper to simplify the task of writing such a code later on. But at first we have to speak about another kind of button : OK button. The property to change is "PushButtonType". Values taken by this property are given by a IDL file as usual :
Listing 25 PushButtonType enumeration : IDL File
// IDL
module com { module sun { module star { module awt {
enum PushButtonType
{
STANDARD,
OK,
CANCEL,
HELP
};
}; }; }; };
The values are given by an enum type. We have already encountered such a problem and then know how to resolve it. I give here the code to add if you want an OK :
//Listing 26 adding a second “OK” button
// C++
// second button : OK button
// we need a second button modedl
Reference< XInterface > xbuttonModel2 = xMultiServiceFactory->createInstance(
OUString::createFromAscii("com.sun.star.awt.UnoControlButtonModel"));
if (xbuttonModel.is()) printf("OK UnoControlButtonModel\n"); else printf("Error ... UnoControlButtonModel\n");
Reference< XPropertySet > xPSetButton2(xbuttonModel2,UNO_QUERY);
if (xPSetButton2.is()) printf("OK XPropertySet\n"); else printf("Error ... XPropertySet\n");
// *** The following property is not position-independant !!!!!
// Don't forget to add : #include <com/sun/star/awt/PushButtonType.hpp>
// Don't forget to add "com.sun.star.awt.PushButtonType \" in the makefile
// short is found with Inspector
val <<= (short)PushButtonType_OK;
xPSetButton2->setPropertyValue(OUString::createFromAscii("PushButtonType"),val);
value=80; val <<= value;
xPSetButton2->setPropertyValue(OUString::createFromAscii("PositionX"),val);
value=70; val <<= value;
xPSetButton2->setPropertyValue(OUString::createFromAscii("PositionY"),val);
value=50; val <<= value;
xPSetButton2->setPropertyValue(OUString::createFromAscii("Width"),val);
value=14; val <<= value;
xPSetButton2->setPropertyValue(OUString::createFromAscii("Height"),val);
val <<=OUString::createFromAscii("Button2");
xPSetButton2->setPropertyValue(OUString::createFromAscii("Name"),val);
xPSetButton2->setPropertyValue(OUString::createFromAscii("TabIndex"),makeAny((short)1));
val <<=OUString::createFromAscii("OK");
xPSetButton2->setPropertyValue(OUString::createFromAscii("Label"),val);
And then we have to add it and then to modify the insert listing's part like that :
//Listing 27 Inserting all control in container
// C++
// insert all the control in container
Reference< XNameContainer > xNameCont(xdialogModel,UNO_QUERY);
if (xNameCont.is()) printf("OK XNameContainer\n"); else printf("Error ... XNameContainer\n");
val <<= xbuttonModel;
// We insert first the button
xNameCont->insertByName(OUString::createFromAscii("Button1") ,val); printf("First\n");
val <<= xbuttonModel2;
xNameCont->insertByName(OUString::createFromAscii("Button2") ,val); //printf("First\n");
// We insert now the text control
val <<= xlabelModel;
xNameCont->insertByName(OUString::createFromAscii("Label1") , val);
