Hello,

I did the test with my Aspose.Tasks and Swing application and I get the following message instantiating in action "com<span style=“background-color: rgb(43, 43, 43); color: rgb(169, 183, 198); font-family: “Courier New”; font-size: 9pt;”>.aspose.tasks.Project project = <span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(204, 120, 50);”>new <span style=“color: rgb(169, 183, 198); font-family: “Courier New”; font-size: 9pt; background-color: rgb(52, 65, 52);”>com<span style=“background-color: rgb(43, 43, 43); color: rgb(169, 183, 198); font-family: “Courier New”; font-size: 9pt;”>.aspose.tasks.Project()<span style=“font-family: “Courier New”; font-size: 9pt; color: rgb(204, 120, 50);”>;"

…

NB: with a sample “static void main (String [] args)” it works well in new Project() !!

Thank you to release me soon.

my code :
public static Project mapping(final IGanttModel modelToExport, ColumnTreeSelection… columnTreeSelections) {
    loadLicense();

    com.aspose.tasks.Project project = new com.aspose.tasks.Project();
    setDefaultCalendar(project);

…
    return null;
}

exist a good compatibility between Aspose.Tasks with Java Swing or Java AWT ?

Hi Billel,


Thank you for writing to Aspose support team.

I have tried to re-produce the scenario using Java swing but no issue is observed in button action and main function. Here a complete Java project is attached which contains swing controls. I have initialized a project in button action and main function. You may please give it a try and share your simple project with minimal code which can be compiled and executed here to observe the issue. It will help us to provide assistance accordingly.

Regarding compatibility comparison of Java Swing and AWT, no difference is found in the documents. Aspose products are independent of GUI controls and impose no restriction on any one of them.
