GTK, blinking interfaces V2

Some manipulations makes TXM interfaces blink. The bugs only happens to GTK3 and Ubuntu 20.04+

To reproduce 1

  • Create a CA
  • Open&Close the chart edition option dialog
  • the interface is blinking when moving the mouse over the corpora area

To reproduce 2

  • Create a specificity and open a chart of some lines OR Create a CA
  • click in the chart ->the border border around the chart is shown
  • place the mouse over the bar and don’t move the pointer for some secs (time for the JFC tooltip to open ?)
  • the interface is blinking when moving the mouse over the corpora area

Solution

restore :

  • for 1) : in OpenJFCChartPropertiesEditor, do not wrap the dialog in SWT async and Swing.invokeLater : makes the dialog modal but the interface is no more broken
  • for 2) : in CustomChartPanel, disable the tooltips for Linux only

fix the Swing blink
