Hide GUI controls before tab is switched?

Recommended Posts

I've a GUI with 3 tabs. The current code (irrelevant bits omitted) is as follows:

#include <ButtonConstants.au3>
#include <ComboConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <GuiEdit.au3>
#include <GuiIPAddress.au3>
#include <GUIListBox.au3>
#include <GuiRichEdit.au3>
#include <Misc.au3>
#include <StaticConstants.au3>
#include <TabConstants.au3>
#include <WindowsConstants.au3>

Global $g_hSAForm = GUICreate($g_sApplicationName, 801, 601, -1, -1)
Global $g_hSATabs = GUICtrlCreateTab(0, 0, 800, 600)

Global $g_hTestTabSheet = GUICtrlCreateTabItem("Tests")
Global $g_hStatusDisplayEdit = _GUICtrlRichEdit_Create($g_hSAForm, "", 9, 30, 782, 266, BitOR($ES_AUTOVSCROLL,$ES_READONLY,$WS_VSCROLL))

Global $g_hIpAddress = _GUICtrlIpAddress_Create($g_hSAForm, 172, 312, 130, 21)
_GUICtrlIpAddress_Set($g_hIpAddress, "")

Global $g_hLogTabSheet = GUICtrlCreateTabItem("Log")
Global $g_hLogDispEdit = GUICtrlCreateEdit("", 9, 30, 782, 511, BitOR($ES_AUTOVSCROLL,$ES_READONLY,$WS_VSCROLL))
Global $g_hSettingsTabSheet = GUICtrlCreateTabItem("Settings")
Global $g_hSvcProfileSettingsEdit = GUICtrlCreateEdit("", 9, 46, 782, 201, BitOR($ES_AUTOVSCROLL,$ES_READONLY,$WS_VSCROLL))


While 1
    Local $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE

        Case $g_hSATabs
            Switch GUICtrlRead($g_hSATabs)
                Case 0
                    _GUICtrlIpAddress_ShowHide($g_hIpAddress, @SW_SHOW)
                    WinSetState($g_hStatusDisplayEdit, "", @SW_SHOW)

                Case Else
                    _GUICtrlIpAddress_ShowHide($g_hIpAddress, @SW_HIDE)
                    WinSetState($g_hStatusDisplayEdit, "", @SW_HIDE)

The first tab contains a RichEdit and a IpAddress (among other GUI elements). Whenever I switch to and from the first tab, those two elements show/hide as intended, but there is a noticeable lag. As a result, for example, I can still see these elements after switching to the third tab for a split second before they disappear. I'm very certain system resource availability isn't an issue.

Is there a way to finish updating these two elements' visibility before the new tab selection is rendered?

As suggested in the Tabs tutorial in the Wiki, I would use ControlShow/Hide like this:

Case $g_hSATabs
            Switch GUICtrlRead($g_hSATabs)
                Case 0
                    ControlShow($g_hSAForm, "", $g_hIpAddress)
                    ControlShow($g_hSAForm, "", $g_hStatusDisplayEdit)
                    ;_GUICtrlIpAddress_ShowHide($g_hIpAddress, @SW_SHOW)
                    ;WinSetState($g_hStatusDisplayEdit, "", @SW_SHOW)

                Case Else
                    ControlHide($g_hSAForm, "", $g_hIpAddress)
                    ControlHide($g_hSAForm, "", $g_hStatusDisplayEdit)
                    ;_GUICtrlIpAddress_ShowHide($g_hIpAddress, @SW_HIDE)
                    ;WinSetState($g_hStatusDisplayEdit, "", @SW_HIDE)

I get virtual instantaneous reaction from the 2 controls that way.
