Introduction

Dialogs (frame windows) can be moved around, resized, hidden, and rolled up while the application is running. MultiColumnLists can have their columns rearranged, resized, and a column can sort its content in ascending or descending order. However closing and then restarting the application will reset these settings to their default values, those specified within a .layout file if one was use, or those specified in code.

This clases saves these attributes into an XML file. When the application restarts the contents of the XML file will be read and the dialogs and MultiColumnLists will be restored to their last states.

Please discuss this snippet in the Storing Dialog Configurations thread on the message board.

Incorporating into Sample_Demo7

This demo contains 3 dialogs. Let's store their configurations.

Add DialogConfigurations.cpp to the Sample_Demo7 project.

Edit Sample_Demo7.h:

• add #include "DialogConfigurations.h"
• add within the protected section: DialogConfigurations m_dialogConfigurations;

Edit Sample_Demo7.cpp to add the following at the end of the Demo7Sample::initialiseSample() function, between initDemoEventWiring(); and return true;:

 m_dialogConfigurations.loadConfigurations("../datafiles/configs/Sample_Demo7.xml", "../datafiles/configs/DialogConfigurations.xsd");
 m_dialogConfigurations.addDialog("Demo7/Window1");
 m_dialogConfigurations.addDialog("Demo7/Window2");
 m_dialogConfigurations.addDialog("Demo7/Window3");

Add the following to Demo7Sample::cleanupSample()

 m_dialogConfigurations.saveConfigurations();

That's it! From now on the 3 windows within that demo will "remember" their previous configurations.

Configuration Attributes

The XML configuration file is loaded by a call to loadConfigurations(). It silently ignores errors within that XML file. The worst that will happen is that some dialogs and MultiColumnLists will revert to their initial values.

Calling addDialog() and passing the window name as parameter will register that dialog to have its configuration written to the XML file. The next call to saveConfigurations() will write the configuration of that registered window such that the next time loadConfigurations() is called the window will be automatically registered.

The second parameter of addDialog() allows you to specify which attributes to monitor. By default every attribute is monitored. However you can specify to monitor one or many of the following, separated by spaces: Position, Visible, and RolledUp.

The addMultiColumnList() function behaves in a similar manner, allowing you to specify which MultiColumnLists which of their attributes to monitor. Again the default is to monitor every attribute but you can also specify one or many of the following: ColumnSequence, ColumnWidths, SortedColumn, and AscendingSort.

Warning: the Demo7Sample::cleanupSample() is never called when exiting the demo, despite what the comments might say. A solution is presented on the message board.

Please discuss this snippet in the Storing Dialog Configurations thread on the message board.
