ListView exStyles: LVS_EX and WS_EX

Recommended Posts

For other controls, I can specify some WS_EX constants in the GuiCtrlCreate*() exStyles parameter.

For ListView, the Help suggests that both WS_EX and LVS_EX constants can be used in the exStyles parameter. But some WS_EX and LVS_EX constants have the same value, e.g. WS_EX_WINDOWEDGE and LVS_EX_FLATSB, so which does GuiCreateListView recognize?

MSDN says, for most controls, "call SetWindowLong" to set exStyles. But for ListView, it says "Use the LVS_SETEXTENDEDLISTVIEWSTYLE" to set extended ListView styles. Am I correct in thinking that GuiCtrlSendMsg(-1,LVS_SETEXTENDEDLISTVIEWSTYLE, exStyles, exStyles) should be called to set LVS_EX styles, not the exStyles parameter of GuiCtrlCreateListView() ?

I am working on making the control styles in Koda more easily understandable. The part I am working on now is native ListView, not the UDF. So replies that deal with the UDFs will not be particularly helpful.

I have always found that applying $LVS_EX_* extended styles to a ListView requires the _GUICtrlListView_SetExtendedListViewStyle UDF command - regardless of whether the ListView is a native or UDF created control. Any extended styles set in the creation function line are treated as the numerically equivalent $WS_EX_* extended styles. ;)

So your suggestion of GuiCtrlSendMsg(-1,LVS_SETEXTENDEDLISTVIEWSTYLE, exStyles, exStyles) seems quite logical. I believe you can set the final exStyles parameter to 0 which then forces the allocation of the first extended styles parameter whcih woudl hold all the required values. ;)

I hope that helps. :)

Yes, it does help.

I have recently learnt that GuiCtrlSendMsg(-1,LVS_SETEXTENDEDLISTVIEWSTYLE, exStyles, exStyles) does the same thing as _GUICtrlListView_SetExtendedListViewStyle(-1,exStyles).
