Revision as of 18:17, 24 May 2006

We want now to construct the dialog box above.

We have to have a look at the corresponding IDL files. We begin with XtextComponent Interface. [cpp] //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.

We show now the 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 : [cpp] //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 : [cpp] //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 helper to simplify the task of writing such a code later on. But at first we have to speak on an other 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 encounter such a problem and then know how to resolve it. I give here the code to add if you want an OK button : [cpp] //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 : [cpp] //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);
