GuiSliderCtrl Modifications

Download Code File

In GuiSliderCtrl.h line 28 add:

bool mAutoSnap;
StringTableEntry mFormat;

In GuiSliderCtrl.cc line 25 add:

mAutoSnap = false;
mFormat = StringTable->insert("%1.3f");

In GuiSliderCtrl.cc initPersistFields, add the following before endGroup("Slider");

addField("autoSnap", TypeBool,   Offset(mAutoSnap, GuiSliderCtrl));
addField("format",   TypeString, Offset(mFormat,   GuiSliderCtrl));

In onMouseDown, add the following at the top

if(mAutoSnap) return;

Later, change

if ((event.modifier & SI_SHIFT) && mTicks > 2) {

to

if ((event.modifier & SI_SHIFT) || mAutoSnap) {

Finally in onRender, change

dSprintf(buf,sizeof(buf),"%0.3f",mValue);

to

dSprintf(buf,sizeof(buf),mFormat,mValue);

I started using this change in my project since I needed things that snapped to integer boundaries in my GUI. Enjoy.
