Hi,
I am currently looking into some memory leak reports and I am finding the
"qx.disposerDebugLevel" very useful.
When looking at the reporting of objects not being disposed (in Object.js,
"Missing destruct definition for...") I see several issues about objects in the
Qooxdoo framework (I am using V1.4.1):
053884 Missing destruct definition for '$$user_behavior' in
qx.ui.table.columnmodel.Resize[undefined]:
qx.ui.table.columnmodel.resizebehavior.Default[503]
053885 Missing destruct definition for '$$user_selectionModel' in
qx.ui.treevirtual.SelectionManager[undefined]:
qx.ui.table.selection.Model[undefined]
053892 Missing destruct definition for '$$user_dataRowRenderer' in
webgui.ui.tree.ComtecTree[undefined]:
webgui.ui.tree.ComtecTreeRowRenderer[undefined]
053892 Missing destruct definition for '$$user_selectionModel' in
webgui.ui.tree.ComtecTree[undefined]: qx.ui.table.selection.Model[undefined]
053893 Missing destruct definition for '$$user_tableModel' in
webgui.ui.tree.ComtecTree[undefined]: qx.ui.treevirtual.SimpleTreeDataModel[482]
053893 Missing destruct definition for '$$user_metaColumnCounts' in
webgui.ui.tree.ComtecTree[undefined]: 1
053902 Missing destruct definition for '$$user_decorator' in
qx.ui.core.Widget[undefined]: qx.ui.decoration.Background[458]
056719 Missing destruct definition for '$$user_tablePaneModel' in
qx.ui.table.pane.Scroller[undefined]: qx.ui.table.pane.Model[undefined]
056723 Missing destruct definition for '$$user_menu' in
qx.ui.table.columnmenu.Button[undefined]: qx.ui.menu.Menu[616]
056729 Missing destruct definition for '$$user_opener' in
qx.ui.menu.Menu[undefined]: qx.ui.table.columnmenu.Button[undefined]
065634 Missing destruct definition for '$$user_toolTip' in
qx.ui.toolbar.Button[undefined]: qx.ui.tooltip.ToolTip[473]
Most seem to have to do with classes I derive from, like "qx.ui.table.Table",
and where I use the construction with the "custom" argument to call the
base-constructor with overrides for the tablePane, selectionModel etcetera. Is
there something I should do in the dispose of my own objects? I was expecting
code like in "qx.ui.table.Table._applySelectionModel" to dispose any selection
model if a new one is set.
Futhermore I have a lot of buttons with a tooltip set using "someWidget.
setToolTip(new qx.ui.tooltip.ToolTip("some text"))" and I didn't expect having
to dispose them myself. I hope you can tell me how I can fix these issues (if
necessary that is).
Thanks in advance.
Best regards,
Jeroen
