SetCtrlAttribute doesn't update ATTR_LABEL_TEXT

[gstemp]

I am calling SetCtrlAttribute(handle, ATTR_LABEL_TEXT, graphcontrolID, "arbitrary text"), but the text label on the graph control isn't getting updated.  I tried calling ProcessDrawEvents(), but that doesn't help.  How do I get the label to change?

the sequence of parameters is wrong in your example, it should read: SetCtrlAttribute ( panel_handle, control_id, ATTR_LABEL_TEXT, "label text" );

Should be:

SetCtrlAttribute (panelHandle, PANEL_CONTROL, ATTR_LABEL_TEXT,  "arbitrary text");

Hi shpanda,

This is the definition of SetCtrlAttribute:

int SetCtrlAttribute (int panelHandle, int controlID, int controlAttribute, ...);

for example

SetCtrlAttribute (panelHandle, PANEL_Control, ATTR_LABEL_TEXT, "text");

It seems that you have first the controlAttribute than your controlID, try to change the other in this way:

SetCtrlAttribute(panelhandle, PANEL_graphcontrolID, ATTR_LABEL_TEXT, "arbitrary text")

Also make sure that the name of handle corresponds to the name of your panel.

Oops.  Thank you.  Just a typo.  That was easy!

SetCtrlAttribute()can't change the control value and display it immediately, when you use the SetCtrlAttribute function, the control will be updated after the dispaly function called, so if you want to chang a control value and display it immediately，you can use the SetCtrVal, this function can implement, but it will take a little long time.

GOOD LUCK
