JavaFX TreeTableView bigger show/hide columns button

Question

Is there a way to make the Show/Hide columns button in the TreeTableView bigger?

Answer 1

Experiment with the following CSS:

.tree-table-view > .column-header-background > .show-hide-columns-button {
    -fx-font-size: 24pt ;
}


.tree-table-view > .column-header-background > .show-hide-columns-button .context-menu {
    -fx-font-size: null;
}

.tree-table-view .column-header, 
.tree-table-view .filler, 
.tree-table-view > .column-header-background > .show-hide-columns-button, 
.tree-table-view:constrained-resize .filler {

    -fx-size: 3em ;

}
