TITLE:: ToolBar
summary:: An inline button bar populated by MenuActions
categories:: GUI
related:: Classes/Menu, Classes/MenuAction, Classes/MainMenu
DESCRIPTION::
A ToolBar is similar to a link::Classes/Menu::, with several key differences:
LIST::
## ToolBars act as regular link::Classes/View::s, and can be placed in layouts or in other views.
## MenuActions on a toolbar appear as buttons instead of being listed menu-style
## By default, MenuActions that have icons show ONLY the icon. MenuActions with text will appear as a text button. This can be changed using the toolButtonStyle property.
::
code::
(
View().fixedWidth_(300).layout_(HLayout(
ToolBar(
MenuAction("Option A", { "Option A".postln }),
MenuAction("Option B", { "Option B".postln }),
MenuAction("Option C", { "Option C".postln })
)
)).front
)
::
CLASSMETHODS::
METHOD:: new
Create a new ToolBar containing one or more actions.
ARGUMENT::
One or more link::Classes/MenuAction::
INSTANCEMETHODS::
METHOD:: orientation
The horizontal or vertical orientation of the ToolBar
ARGUMENT::
A link::Classes/QOrientation::
METHOD:: toolButtonStyle
Controls whether the toolbar shows icons, text, or both.
ARGUMENT::
An integer; one of the values of link::Classes/QToolButtonStyle::.
DISCUSSION::
CODE::
(
~icon = Image(64).draw({ Pen.fillOval(Rect(0, 0, 64, 64)) });
~styles = QToolButtonStyle.classVarNames;
~tool = ToolBar(
MenuAction("Text")
.icon_(~icon)
.action_({
~tool.toolButtonStyle = (~tool.toolButtonStyle + 1) % ~styles.size;
~styles[~tool.toolButtonStyle].postln;
})
).front;
)
::
EXAMPLES::
code::
(
s.waitForBoot {
~synth = nil;
~freq = 300;
~startIcon = Image(40).draw({
Pen.fillColor = Color.green;
Pen.moveTo(5@5);
Pen.lineTo(35@20);
Pen.lineTo(5@35);
Pen.lineTo(5@5);
Pen.fill;
});
~stopIcon = Image(40).draw({
Pen.fillColor = Color.red;
Pen.fillRect(Rect(10, 10, 20, 20));
});
~freqMenu = Menu(
MenuAction("100"),
MenuAction("200"),
MenuAction("300"),
MenuAction("400"),
MenuAction("500"),
).title_(~freq);
~updateFunc = {
|obj, what, action|
if (what == \triggered) {
~freq = action.string.asInteger;
~freqMenu.title = ~freq;
~synth !? { ~synth.set(\f, ~freq) };
}
};
~freqMenu.addDependant(~updateFunc);
~play = MenuAction("play")
.icon_(~startIcon)
.action_({
if (~synth.isNil) {
~synth = { |f| SinOsc.ar(f) * 0.1 }.play(args:[\f, ~freq]);
~synth.onFree { ~synth = nil };
~play.icon = ~stopIcon;
} {
~synth.free;
~play.icon = ~startIcon;
}
});
~toolBar = ToolBar(~play, ~freqMenu).minWidth_(200).front;
~toolBar.onClose_({ ~freqMenu.removeDependant(~updateFunc) })
}
)
