The cmd.tool.hand-icon stays highlighted/activated SOLVED

[mbz]

Hey guys!
I've inserted an custom command with an icon to the cmdbar.standard. I'd like to get the behavior like the cmd.tool.hand. I mean, I'd like to switch between the cmd.tool.hand and my cmd.tool.myCustom.
The problem is, it does not switch. The cmd.tool.hand-icon stays highlighted/activated. Is there any flag or something I need to add to my command? I cannot find any solution in this forum neither.

Thanks
mbz

Hello mbz,

Well the selected state of the Hand Tool is indicated by the UIX_CmdItemState_Checked flag of the UIX_CmdItemState enum. The unselected state is a normal state of the command UIX_CmdItemState_Normal. Basically, when you check your item, you must set the Hand Tool's state to UIX_CmdItemState_Normal and visa versa.
All of this should be done in the custom command handler:

Hi Alex,
Thank you for your reply.

Unfortunately that solution doesn't work for me. I need to change the CmdItem.State in OnNotify (when my button is pressed). Something like that:

Code: Select all

public void OnNotify(int nCode, IUIX_Cmd pCmd, IUIX_CmdItem pItem, IUIX_Obj pOwner, uint nNotifyData)
{
    var handCmdId = _inst.Str2ID("cmd.tool.hand", false);
    var customCmdId = _inst.Str2ID("cmd.tool.myCustom", false); 
    
    if (pCmd.ID.Equals(handCmdId))
        pItem.State = (int) UIX_CmdItemState.UIX_CmdItemState_Checked;
    else if (pCmd.ID.Equals(customCmdId))
        pItem.State = (int) UIX_CmdItemState.UIX_CmdItemState_Checked; 
}

and visa versa.
But pItem.State is readonly. I need the same behavior for my CmdItem, like cmd.tool.hand and e.g. cmd.tool.selectText have, only one of them can be checked.

Maybe my way of thinking is wrong.

Thanks,

Hello mbz,

The state of the command item should be modified in the OnGetItemState method.

Hi Alex,

Well, I did understand that. The problem is, OnGetItemState is only called, when the cmdbar is drawn. Never after the OnNotify was raised.
So, maybe you can tell me when this method is called.

Hello mbz,

The state of the command item can only be updated from the OnGetItemState method. This means that you'll need to know the state for each separate item in that point. You can try to redraw the command items so that their state will refresh:

Hi Alex,

Well, the pItem.Redraw() doesn't raise OnGetItemState neither.
Maybe you can show me how it is done in your code. It shouldn't be such a big problem to change the item state to inform the user, which tool is activated right now.
If switching between Hand Tool and Select Text is working fine, why is it such a trouble with an custom item then?

Thank you for your help,

Hello mbz,

I will try to do this and will write back whether it's possible.

Hi, mbz.

Well, the pItem.Redraw() doesn't raise OnGetItemState neither.

To update states of command-items on toolbars, use:

Code: Select all

PDFXEdit.IPXV_Inst Inst = pdfCtl.Inst;
PDFXEdit.IUIX_Inst uiInst = (PDFXEdit.IUIX_Inst)Inst.GetExtension("UIX");
...
int flag = (int)PDFXEdit.UIX_CmdItemUpdateFlags.UIX_CmdItemUpdate_State;
uiInst.CmdManager.UpdateCmdItems(flag, Inst.Str2ID("cmd.tool.hand"));
uiInst.CmdManager.UpdateCmdItems(flag, Inst.Str2ID("cmd.tool.myCustom"));
