** Description changed:
gtk_paint_box() crashes X Server
############################################
+ When I was resizing a window in IBM Lotus Notes, the desktop logout
automatically. After some investigation I found that X server crashed when
gtk_paint_box is called; when the application trying to repaint its scroll bar
box.
+
+ Simple codes like:
+
+ void DrawGtkScrollBarTrough(GdkWindow* window, GdkRectangle* rect,
GdkRectangle* clipRect,
+ GtkStateType state, GtkOrientation orientation)
+ {
+ GtkCriticalSection ____s;
+ EnsureDummyWidgets();
+
+ GtkWidget* widget = (orientation == GTK_ORIENTATION_HORIZONTAL ?
s_hScrollBar : s_vScrollBar);
+ GtkStyle* style = widget->style;
+
+ pFile = fopen("/home/notes/mylog", "a");
+ fprintf(pFile, "Begin DrawGtkScrollBarTrough, gtk_paint_box(style=0x%x,
window=0x%x, state=%d, GTK_SHADOW_IN, clipRect=0x%x, widget=0x%x, trough,
rect->x=%d, rect->y=%d, rect->width=%d, rect->height=%d, \n", style, window,
state, (int)clipRect, (int)widget, rect->x, rect->y, rect->width, rect->height);
+ fclose(pFile);
+
+ gtk_paint_box(style, window, state, GTK_SHADOW_IN, clipRect, widget,
+ "trough", rect->x, rect->y, rect->width, rect->height);
+
+
+ pFile = fopen("/home/notes/mylog", "a");
+ fprintf(pFile, "END DrawGtkScrollBarTrough\n");
+ fclose(pFile);
+ }
+
+
+ I checked the parameters passed to gtk_paint_box but didn't find any invalid
values, anyway I'm pasting the values here:
+ ......
